Reportviewer Date Parameter And Calendar.. Not Working And Javascript Errors??

Hi, I've got this ssrs 2005 report that works great passing a few
security related parameters from asp.net codebehind. However, there
are two date related parameters that won't be coming from my web form,
but rather from the report form itself. When I test the report's date
parameters from visual studio it work fine, but when I attempt the
same report from a reportviewer no matter what input I place on the
report's date fields or even if I select the date picker, the report
simply resets to default and reloads. And actually the date picker
from the reportviewer does not not even pop up.



Here's my aspx code:


<%@ Page Language="VB" AutoEventWireup="false"
Inherits="_ReportViewer" MasterPageFile="~/Main/MasterPage.master"
CodeFile="~/Reports/CashSales.aspx.vb" Title="Cash Sales" %>


<%@ Register Assembly="Microsoft.ReportViewer.WebForms,
Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>


<asp:Content ID="Content1" ContentPlaceHolderID="Content1"
runat="Server">
<rsweb:ReportViewer BackColor="Transparent" ZoomMode="PageWidth"
Width="100%" ProcessingMode="Remote" ID="ReportViewer1"
runat="server">
<ServerReport ReportPath="/Retailer/CashSales"
ReportServerUrl="http://myserver/reportserver" />
</rsweb:ReportViewer>
</asp:Content>


Note: I'm only passing the parameters that are not coming from the
reportviewer form.




the code behind:




Imports system.web.security.membership
Imports system.web.security.Roles
Imports Microsoft.Reporting.Webforms


Partial Class _ReportViewer
Inherits System.Web.UI.Page
Private Users As New Retailer.Core()


Protected Overrides Sub OnLoad(ByVal e As EventArgs)


Dim Roles() As String =
GetRolesForUser(Page.User.Identity.Name.ToString)


Dim cred As New Retailer.ReportServerCredentials("myuser",
"mypassword", "mydomain")
ReportViewer1.ServerReport.ReportServerCredentials = cred


Dim param As New ReportParameter("r_user",
Page.User.Identity.Name.ToString)
Dim param2 As New ReportParameter("r_role", Roles(0))
Dim p() As ReportParameter = {param, param2}


ReportViewer1.ServerReport.SetParameters(p)
ReportViewer1.ServerReport.Refresh()


End Sub
End Class



on my reportviewer form, at the top I have parameters for startdate
and end date, they are not set to internal or hidden.

If I select the calendar icon, i get a javascript error


Line: 606
Object Required


When I attempt to debug I get a Just-In-time failed : Unspecified
error. Check the documentation index for 'Just-in-time debugging,
errors' for more information. So pretty much I can't see the error or javascript in question.


If i enter anything in the date fields, it disregards them setting them to the defaults.

Again, if i run the report from my vs.net client (not using reportviewer), i can select the calendar and enter dates and it respects them.

Any chance I need to patch sql server or reporting services? maybe ie. I'm on IE 7.0.5730.11
Could my problem be that selecting items on the report itself fails to send my credential information from my codebehind?


Thanks for any help or information!
