JSF :: CDI With Primefaces Charts Not Rendering Properly
Jun 3, 2014
I have 4 Primefaces bar charts which sometimes renders, sometimes not. In one of them, I inject a http user session attribute and use it to render the chart (the idea is to show only the data that corresponds to the (logged in) user department).
There are 4 session beans which I'm using the javax.enterprise.context.RequestScoped. Sometimes, the Glassfish destroys the instance as expected, but sometimes not.Based on Exception below, how can I resolve it?
The xhtml below shows the main code for only 2 of the 4 bar charts:
<p:tab title="Horas de Treinamento (por Funci)" closable="true" >
<p:barChart id="horasBars" value="#{chartHorasFunci.modelHoras}"
legendPosition="ne"
orientation="horizontal"
seriesColors="AA5555, 00438F"
xaxisLabel="Horas" yaxisLabel="Funcis"
title="34 Horas de Treinamento (Orçado/Realizado) por Funci"
[Code] .....
The Exception:
SEVERE: Error Rendering View[/capacitacao/capacitacao/index.xhtml]
javax.el.ELException: /WEB-INF/include/capacitacao/capacitacao/List.xhtml @145,38 value="#{chartHorasFunci.modelHoras}": org.jboss.weld.exceptions.WeldException: WELD-000049 Unable to invoke private void br.com.bb.upb.diage.atb.capacitacao.beans.ChartHorasFunci.initialize() on br.com.bb.upb.diage.atb.capacitacao.beans.ChartHorasFunci@3e9c727c

I'm trying to create a simple bar chart from integer values (measuring number of bulldozers) stored in a mySql DB, in the following schema:
Integer rigId PK;
Integer rigQty;
Date recordDate;
String country FK;
I want to plot the date on the x-axis and quantity on y-axis. I can't seem to find any examples of how to render charts from a database. I just find the generic Primefaces 4.0 examples which uses static data like this:
private void createCategoryModel() { // category chart
categoryModel = new CartesianChartModel();
ChartSeries boys = new ChartSeries();
boys.setLabel("Boys");
[Code] ....
I'm really not sure how to adapt the above to a database method nor have any web searches produced useful examples. I tried something like this, but how to find examples or the type of methods I need to use to create a bar graph from Db values:
@ManagedBean(name = "chartb")
@SessionScoped
public class BarChartBean {
private final Map<Integer, Map<String, Number>> rigNums = new HashMap<>();
// private final Map<Integer, Map<String, Number>> HorasOrcadasPorFunci = new HashMap<>();
private CartesianChartModel cartesianChartModel;
[Code] ....

I have datatable with live scrolling enabled.The columns are not getting sorted fully.When one of the columns is sorted,for example "insured" in the image shown below, all the records seem to have sorted but when i reach the end of scroll and next set of records get loaded i see other records in unsorted order as indicated in the image ,when i try to see the column in descending order.So because of this i am not getting the sorting feature accurately done(All records are not getting sorted at a single stretch)
My JSF code snippet
<p:dataTable id="workSpaceList" var="data"
value="#{workSpaceBean.lazylpId}" widgetVar="multiSelection"
selection="#{workSpaceBean.selectedRows}" resizableColumns="true"
liveScroll="true" scrollRows="15" scrollWidth="100%"
scrollHeight="75%" styleClass=".ui-datatable-hor-scroll"

When I add an array of action-objects (the class extends AbstractAction)
to a combo box, I do receive the action performed events, great!
But the combo box items show the long string of the action object, of course!
How to render that string in a way that only the Action.NAME appears?
I was experimenting a little, but could not make it to work:
Java Code: private class ComboRenderer2 extends BasicComboBoxRenderer {
@Override
public Component getListCellRendererComponent(JList list,

I have a student class with fields names and Gender. Now, I have a students' array. such that I can create multiple students' classes: student a, student b, student c e.t.c and store them into the students' array. Now, I store this students' array in a JComboBox and want to only display the names of these students in the array. Such that the JComboBox lists only the names of student a, student b and student c. . When a user clicks on a selected Item on the JComboBox, even though, it was a student's name that was selected, I want the selectedItem to be a object of the Student class. This, I have learnt works with JList by writing your own custom JList models and then DefaultListCellRenderer. Is there anyway, one could also do this with JComboBox?
//Main Method
import StudentList;
import Student;
import ViewGui;
import Controller;
public class SwingMainMethod {

I have a problem I must solve and could not find an answer after a couple weeks of research, so here I am. I have created a custom Table Cell Renderer than extends DefaultTreeCellRenderer. The mission of this renderer is to set the branch icons depending on conditional statements. There are 3 conditions, and each one should render a different icon. These conditions must be tested against all branches in the tree. This means that using something like setOpenIcon() and setClosedIcon() will not work since it seems as though these methods set all branches to a specific icon (I could be wrong about that though). Below is the code for my custom. I made comments so it is easier to understand what I want to happen and what is not happening.
/**Custom Cell Render that will set the icons for the tree branches and the leafs*/
private TreeIconCellRenderer extends DefaultTreeCellRenderer{
public Component.getTreeCellRendererComponent(JTree tree, Object value,boolean selected,boolean expanded, boolean leaf, boolean row, boolean hasFocus){
//Get defaults in case there is no need to renderer
[Code] ...
What I really need to know is why the renderer is not differentiating between the leaves and branches. The logging statements I have added confirm that the branch block of code does not execute.

I'm currently working on a project which requires to have text displayed along a curve. If found this entry a good starting point. It works fine for me on my develompment machine, however the customer on his machine noticed some issues.
The basic idea is to define a path for the text, explode the text into the separate characters and animate them along the path the fraction of the character of the whole lenght. So with a animation duration of 10 seconds and a label of ten characters, the first character would be animated along 1 second, the second 2, and so forth.
This is done by jumping to the designated time in the animation, start the animation and stop it immediately.
Now the problem as I see it, for stopping the animation a separate timer is used, so it can happen that at the time the animation is actually stopped, the animation moved further than the first frame. The effect is that the last characters of the text appear in front (wrapped around).
As I have no evidence to prove or disprove my theory, what do you think is this plausable? I can see a workaround for this issue by defining a path for each character and then let the animation run to the end. While I can set the duration of the animation to 1 ms which should not be visible to the human eye, I'm not able to make the characters invisible and turn the visiblity on when the animation finishes, they always become visible at the start.
Or create my own animation/transition for placing the characters.

I am fairly new to FX but well experienced with Swing. Since I am familiar with the Swing concept of rendering a let's say JTree I got problems with the FX model of - in this case - TreeView.
I read several documentations about FX. From the API doc of TreeItem I adapted the file browser example to create an own class like this :
public class PathTreeItem extends TreeItem<PathTreeItem> implements
Comparable<PathTreeItem> {
private boolean firstVisit = true;
private boolean readable;
private boolean dir;
private boolean symlink;
[Code] ...
But this did not change anything. I try to override toString() in both classes but even this did not change anything.
What I wonder so far:
Why is item in PathNodeTreeCell always null?What is the difference between the item I get in the updateItem method and the one I get from getItem() (line 10)How can I connect the PathTreeItem class to the PathNodeTreeCell classShould I always call super() in the constructors? (I delved a little bit in the sources of TreeItem and TreeCell and I found some setup code there )Is it ok to extend TreeItem in the way I does for my custom PathTreeItem class? ( I wonder if this is a cyclic dependency when I extends TreeItem in this way )How can I sort the nodes? I added the Comparable interface but this not change the sorting of the nodesAre ther some tutorials of TreeItem/TreeCell with no trivial objects like String ?
I want to adapt an well running Swing application to FX. In the Swing app I used a mechanism to load the child path's of a directory in a separate thread to avoid freezing if the UI if there are much child elements. I guess in FX I should use the Properties pattern to achieve this should I?

I'm new to JavaFX and I'm exploring its 3D capabilities, and in particular the TriangleMesh visualisation.
I have developed a very basic application, based on the Molecule Sample Application provided in the examples, that read a mesh file generated by an external tool (Gmsh) and displays it. Pretty basic.
My problem is that the rendering is not what I expected (see attachement)
My guess is that I got something wrong with the texture coordinates or the triangles orientation.
- I don't what to have textures attached to my meshes. These are 3D meshes used for scientific simulation purposes. I thus have set all texCoords to 0.
- I don't control the orientation of my triangles, they are generated by Gmsh. Their orientation is also not interesting for my end users so I would like to display all triangles the same way. I used the meshView.setCullFace(CullFace.NONE); method.

I would like users in an application to be able to access and edit their user profiles (Application A). The problem is that the user objects (entities, dao, beans) are handled in a separate application (Application B) which is specifically for managing user accounts. Importing the java sources for App B into App A could be messy and might need configuration of the persistence unit and connection. I'm thinking it would be better to inject an EJB from App B to App A to query the user DB and return the results so a user profile form is rendered in App A.
I know how to inject EJBs within the same application, but I'm not so sure about how it's done across different applications or even if that's the most advisable way to achieve what I want. it's better practice to inject an external EJB into App A or simply import the classes from App B and use those.
@Stateless
public class UsersDaoImpl implements UsersDAO {
@PersistenceContext
private EntityManager em;

I have a big issue to render this html page with the webview component :
<html><head lang="en"> <meta charset="UTF-8"> <title>Pb Rotate</title> <style type="text/css"> #myDivRotate {
color: purple; background-color: #d8da3d; height: 200px; width: 300px; margin-top: 20px; margin-left:20px; -webkit-transform:perspective(400px) rotateX(30deg); -webkit-backface-visibility: visible; }
</style></head><body> <div id="myDivRotate"> Coucou
</div></body></html>
The problem is from "perspective" in -webkit-transform. Without it's ok. But with this one, the result is different from a standard browser like chrome or safari.

Untitled.jpg I have been working over this game lately, and i have managed to render multiple images from an array. in this fashion. I created a Main() class with the following in it:
public Main() {
for (int i = 0; i < fuel.length; i++) {
Random r = new Random();
changef = r.nextBoolean();
y = (-600 * i) + r.nextInt(300);
if (changef)
fx = 325;
else
[Code]...
Also, this is the Fuel image class and Obstacle image class:
public void tick(Player2 p2) {
y += dy;
Random r = new Random();
if(x >= p2.getH()) {
y = -40 - r.nextInt(700);
[Code]...
(Fuel and obstacle class are identical but separate for better accessibility) I even have player class with an image listening to key events and also a scrolling background. The problem is when i run the game, the images of obstacles render themselves as i want, except for that they overlap each other, i need to prevent over lapping of this images. The fuel is read and obs is black. Heres a glance of how it looks.

I have some troubles rendering images to the printer, any resolution does not work, even 72 in PDF printer does not work, the image is crappy.
I use the following code but the result is not good. I mean the image quality is not acceptable.
img=new ImageIcon("c:\test\m.jpg").getImage();
scale=72/300d;
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);
I've also tried :
img=new ImageIcon("c:\test\m.jpg").getImage();
AffineTransform aft=g.getTransform();
double scale=aft.getScaleX();
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);
The result is the same even if I change the image, very poor and unacceptable!

As implied by the title, when I am rendering images of the type "BufferedImage" unto a Swing application, the images' pixels are not consistent in size. Some might be larger than other, and some might be smaller than other.
Here is a screenshot of what I am talking about (you might need to zoom in a bit because the image is so small): [URL] ....
And here is also some code for you. The images are actually from a sprite sheet, which I first load in its entirety and then split up in an array.
Java Code:
public static BufferedImage sprites[];
...
public void loadSprites(){
try{
BufferedImage bigImage = ImageIO.read(new File("SOURCE/BLA/BLA/THIS/IS/ACTUALLY/NOT/THE/REAL/SOURCE/IN/CASE/YOU'RE/WONDERING/I/JUST/DON'T/WANT/YOU/TO/FIND/ME/AND/RAPE/ME"));
sprites = new BufferedImage[16 * 16];
[Code] ....
So, how do I make the pixels equally small?

Really need some simple and complete example on how to extends components (graphically and functionally) for primefaces 5.
For example I can't figure how to add custom attributes to existing component or define default values for existing attributes.
Is there any tutorial or a basic common way to achieve this goal or each component have to be extended in its way?

So the following is my code for the Terrian Generation of my game, however the way i have it rendering all the tile rectangles as opposed to just rendering whats visable on my JFrame causes lots of lag.
These are the variables and Rectangles inside _TerrianGen.class
//CHUNK
static int chunkx =2048;
static int chunky =2048;
//RECTANGLES
public static Rectangle[][] tile = new Rectangle[64][64];
static int[][] blockType = new int[64][64];
//0=Grass 1=Dirt 2=Stone 10=Brick 11=Coal 12=Iron 21=Gold 22=Diamond -1=null
This is the Init() code
for (int x =0; x < chunkx-32; x+=32){
for (int y=0; y < chunky-32; y+=32){
tile[y/32][x/32] = new Rectangle(x, y, 32, 32);
blockType[y/32][x/32] = -1;

I'm having some problems styling the PrimeFaces upload tag <p:fileUpload /> in my application.
In my xhtml code I have the following:
<p:fileUpload id="fileUpload" fileUploadListener="#{filters.upload}"
allowTypes="#{filters.uploadTypes}" invalidFileMessage="#{filters.uploadBadType}"
sizeLimit="#{filters.uploadSize}" invalidSizeMessag="#{filters.uploadBadSize}"
update="fileUpload fileTable filterTab uploadMessage hiddenNum hiddenPhoto uploadError footer
namePhotSystem checkOverwrite"
description="Select Text File" disabled="#{filters.fileuploadDisabled}" fileLimit="1"
fileLimitMessage="You are only allowed to upload one file at a time"
styleClass="fileUploadClass" label="Choose the File to Upload" auto="true" />
This all works correctly, both the AJAX update and on the server, but I'm unable to get the button or buttons displayed in the way I need.
By including the following in my CSS:
.ui-fileupload.fileUploadClass {width:428px;}
.ui-icon-plusthick {display:none;}
.ui-button-text {width:200px; height:20px;}
the first sets the width of the button bar, and by looking at the HTML code generated by PrimeFaces, I discovered that the second hides the "+" to the left of the "Choose" button, which here has been replaced by the text "Choose the File to Upload". However, this text is displayed on two lines, with the word "Upload" on the second. I want the whole text to be on one line, but no matter what I do, I cannot get this to work properly. The third line of my CSS code does indeed reduce the height of the button, but the width does not work at all, and the last part of the text is simply lost. How do I put all the text on one line and adjust the width of the button?
Another question is that when I remove the auto="true" attribute from the tag, which I had originally, the "Upload" button is displayed to the right of the "Choose" button, and when a file is chosen but not yet uploaded, it is displayed below the button. This is a capability that I might still want, however, I am unable to style the display, and in particular the progress window to the right of the file name and size. All the files I want to upload are relatively small text files, and I want to adjust this window or even hide it completely. How is this done?
Incidentally, because the files are all quite small, I have disabled the display of the "Cancel" button, so either only the "Choose" button is shown, or the "Choose" and "upload" buttons.

Currently I am having difficulties styling a particular prime faces element in a JSF application for work. I'm tasked with giving the ui a styling and color scheme acceptable to our project design. However I am finding myself unable to "hook" a particular pf element with an ID so that I can proceed with styling a imported .css file.
I'm trying to style the commandLink button to display in Orange 20px font with Italic but when I inspect the element in chrome after being rendered It doesn't even show its style linked to the assigned ID. The class style for mainMenuItem is being applied to the commandlink but is immediately over written by ui-widget. I'm trying to style that one single component(override/replace ui-widget with the properties in the #loggedInUserID)
Current .XHTML code and the css file has been linked with
<h:outputStylesheet library="css" name="masterPW.css"/>
<div class="mainMenuItem"><p:commandLink id="loggedInUserId" styleClass="maserPW.css" value="#{loginController.userFullName}"/>
</div><!--End of mainMenuItem-UserID div -->

I am developing one form in jsf/primefaces. I have two inputText(inputMask) for e.g moble number and telephone number. I want to restrict the user to put only one of these two fields . That means if user starts putting value in mobile no. then telephone no. field should be disabled and if user starts putting value in telephone no. then mobile no. field should be disabled.
how should I do this.

I have an JSF that uses primefaces accordion snippet. However I want to populate the information from each tab from a seperate webpage that would also have accordion snippet in it. I can do this on a single page no problem, but the length of the program (webpage) is getting to the point that it is unmanageable.
The code I have:
<p:layoutUnit position="center">
<p:accordionPanel activeIndex="null">
<p:tab title="Burglar">
<h:outputText value= "Burglar"/>
<p:accordionPanel activeIndex="null">
<p:tab title="Skills">
<h:outputText value= "Skills"/>
[Code] ....
What I am after:
<p:layoutUnit position="center">
<p:accordionPanel activeIndex="null">
<p:tab title="Burglar">
<h:outputText value= "Burglar"/>
<p:accordionPanel activeIndex="null" url="burglar.xhtml">
</p:accordionPanel>
[Code] ....
How to get this to work... I am sure that it has something to do with my url but not sure how to fix it and I can not find anything on the web on how to do this.
