JavaFX 2.0 :: Sometimes Form (BorderPane) Does Not Show Correctly
Feb 11, 2015
We have a problem with a JavaFX application running on Java 7. Sometimes a form (BorderPane) does not show correctly – it seems to be transparent (i.e. content previously shown at the same place is still visible). Controls seem to be present and respond to events – e.g. we can close the form by blindly clicking the appropriate button. Once the issue happens it is persistent, i.e. next time we open the form, it behaves the same.
We have no reproducible scenario leading to the issue. It just happens here and there – we have not been able to identify any pattern yet.
Additional information:
The form (BorderPane) is loaded during application start-up but it is not shown initially,to show the form we remove previous contents from a StackPane and add the form instead,to hide the form we do the reverse.

I have a JSP which will let a user register for an account at my website. If the user submits wrong or illegal info into the JSP, then I want to return the same JSP with an appropriate error message next to/above each wrongly filled (form) fields.
If possible, highlight the wrongly filled form field - this feature is not necessary though.
I have given a sample below to show what I need. I understand that the sample must be using something like javascript, but I don't know all that client side scripting. I only want to use JSP to do it. As I said, I want to sort of return the JSP form to the user after marking all the mistakes and how to correct them.
How do I do this ?

I'm having a problem with SplitPane (horizontal Flow). What I'm looking for is to find a way to maintain the left pane in the same position when the main window maximizes. I do not want the left pane to grow on its width. If I go into the AnchorPain Constraint in the Scene Builder and remove the right and left constraints, when I run the application, the left pane keeps its position, but it appears a gap between the two panes (the left pane and the right one).
I need to find the way to expand the right pane to the position where the left pane is.
The link shows an image that illustrates the problem. [URL]

When I lookup a RadioMenuItem, I can not cast it to a RadioMenuItem. With other nodes like normal RadioButtons etc. this works.
This works:
Node x = (Node) B2_GridMenuButtonFX.lookup("#id);
This does not work:
Node x = (Node) B2_GridMenuButtonFX.lookup("#id);
Instead I see the warning: "incompatible types: Node cannot be converted to RadioMenuItem".

I have the below snipped of code that is giving me problems. The code is called when the user clicks on the "NEXT" button of the form. Why despite getting into the Lines 41-45 I am not able to update the BorderPane? Lines 30-39 appear to work as expected. In the case below there are 3 entries within the TreeMap. You can see this within the Output provided by NetBeans shown below.
NetBeans Output
Next Button Clicked.
1 => BorderPane@5bee8c9b <----------- Entry 1
Next Button Clicked.
1 => BorderPane@5bee8c9b <----------- Entry 1
MATCH!
2 => BorderPane@e857ac <------------ Entry 2
UPDATING! BorderPane@15d3ddab <------------ Entry 3
Cancel Button Clicked.

I would like to reopen the following discussion: Show SVG-Image in WebView (JavaFX 8)
In our IDE (Eclipse Luna) running with jdk1.8.0_25 we load a html page into the webengine. The html page contains <img> tags with '.png' and '.svg' as src. Everything looks fine.
But if we execute the programm with java -jar, the WebEngine doesn't display the svg-files. Instead it shows the 'File not find'-Icon. The .png files still work
The files are definitly included into the jar and will be displayed if we link to them via <a href="someSvg.svg"></a>
So why it doesn't work.

I only want the context menu to be showen if the user is clicking on an actual listview item, not if they click anywhere else in the listview. I know this is possible and I found answers to similar problems, but in the end they didn't provide enough infomation for me to solve my issue. I found this example on how to do it with a list view containing String objects, but what if my list view contains another object, in my case a wrapper class? I have a wrapper class to keep track of the key, but I only display the value variable in the listview, through calling the toString method. So the cells still contain a wrapper.
class Wrapper(int key, String value) {
..
}
public String getValue() { return value; }
public SimpleStringProperty getValueAsProperty() { return new SimpleStringProperty(value); }
public String toString() { return value; }
[Code]....
But line 05 gives me a NullPointerException, why? I do this after I've set the items of the list view by doing listView.setItems(..).

I'm trying to add a tooltip on a cell of a TableView in order to show some information to the user.
This is the code:
colonnaColore.setCellFactory(param -> {
TableCell<Appuntamento, Template> cell = new TableCell<Appuntamento, Template>() {
@Override
protected void updateItem(Template item, boolean empty) {
// calling super here is very important - don't
[Code] ....
In few words: there is a cell factory on the cell to show a colored box, then I added a tooltip to the cell. I need informations that are in the item added to the TableView that has type "Appuntamento". So I try to get my element with these code (that in others part of my code works); but here I get a Null Pointer Exception on cell.getTableView() and also on cell.getTableRow().
I'm probably using these methods in a way that was not expected.

I have a form containing several fields, 2 of which persist to different table in a database than the rest of the fields on the form. I have no problem persisting the data into both tables of the database, and after the form is submitted I reset the form to its default values. That all works fine.
But in the same session, when I open another form (a search form) and enter search criteria, which then displays a datatable containing the search results, those 2 values that are persisted to another table are not showing up, but the rest of the data is.
Here is the method that calls the persist methods:
@ManagedBean(name = "foreignPartyController")
@SessionScoped
public class ForeignPartyController implements Serializable {
...
public void saveData() {
[Code].....
The values do show up, but the problem is, when a subsequent form is opened in the same session (e.g. a search form) the field for that value shows the actual value, instead of the field being blank.'
I am not sure why the data from the one database ("parent") is showing up, yet the data from the other database ("child") is not.
Is it something I am doing wrong? I thought by setting the setter in the child controller class back to a new instance of the Entity class (PolicyPayment) that it would reset the form to default values, but at the same time retain (or save) the inputted values in the same session.

I have a button on UI which adds messages and when the user clicks on it the form gets submitted, meanwhile the user is clicking on refresh(F5) multiple times which is causing the same message to be displayed multiple times. To resolve this , I am converting the form from a synchronous submit to Asychronous but it is still not working. Below is the code:
Code before:
<td><input class="buttonred" type="submit" value="Confirm Add" name="submit_message"></td>
<s:form action="upd-message" method="POST" validate="true" onsubmit="validateMsg();return false;" enctype="multipart/form-data">
function validateMsg() {
var frm = document.forms["upd-message"];
frm.actionType.value=message;

try(BufferedWriter bw = new BufferedWriter(new FileWriter("temp.txt"))){
for(StringBuilder row:objectToOutput) bw.write(row.toString());
}catch(IOException e){}
[code]....
Why don't the a's show up on the console? I put them in as part of the debugging process and now I don't understand why they don't show up in both places.

I am currently trying to make a method that will enable a jLabel to be dragged across the screen. I want to be able to drag the object pretty much anywhere on the screen(I hope to eventually make a destination for it where it can be dropped but I will get to that later). I have looked on various places on the internet on how to achieve this and the most simple solution does something like this:
Java Code:
jLabel6.setText("jLabel6");
jLabel6.addMouseMotionListener(new java.awt.event.MouseMotionAdapter() {
public void mouseDragged(java.awt.event.MouseEvent evt) {
jLabel6MouseMoved(evt);
}
});
private void jLabel6MouseDragged(java.awt.event.MouseEvent evt) {
x = evt.getX();
[Code]...
This actually works somewhat but it is very faulty. For example the jLabel keeps appearing and reappearing as I drag it. Furthermore when I drag it I can see a duplicate Jlabel being dragged as well in the top left hand screen. So how might I fix this?

I am trying to write a date program. I have it written and running correctly, except one issue. I cannot get the numerical date to display correctly. I know it is an issue with printf. I don't know anything about printf. Here is my method to return the day
public int getDay() {
return day;
}
When it returns, it is literally returning just the numeric date. I need it to show up as 02 or 03 instead of 2 or 3, respectively.
