<TD NOWRAP WIDTH="100%">
<INPUT TYPE="HIDDEN" ID="control_type" VALUE="hidden">
<INPUT TYPE="HIDDEN"
NAME="myid"
VALUE="12"/>
<INPUT TYPE="HIDDEN"
ID="myid_displayText"
VALUE="12" />
</TD>
I found that worked great for the first pass, i could assign
MyTest.toString() to dataset parameters without ever having to set overall
report parameters. However, in the viewer I wasn't able to generate a
PDF, Excel etc. I would get a stack trace like this:

How do the AJAX controls work? Obviously the request is gone after the
web report is displayed. Is this the reason for the hidden parameter
variables in the first place? If what I'm trying to accomplish can't be
done what is the purpose of using the application context object? Is it
just to get objects inside the report and script them to report
parameters? Or can you only use the application context object to display
the first report?
Any help would be greatly appreciated as I don't have much hair left to
pull out.
Kindest regards,
Shayne

Shayne,
I see what the problem is now. This appears to be an issue with how the
ajax framework is building its url to submit exports and other things.
As a work around you could open the framesetfragment.jsp page and add
the following:
var qstring = "<%= request.getRequestURL() %>" +
"?<%=request.getQueryString() %>";
right above this line:
var soapURL = document.location.href;
Then open the BirtExportReportDialog.js and change this line:
var action = soapURL;
var action = qstring; //soapURL;
This code will most likely have to be changed in other locations in the
AJAX framework, so I will open a bugzilla entry for this issue. A
better option in your case is to add your object to session and retrieve
it that way.

Put this in the onCreate of the label. beforeFactory is called before
the onPrepare event.
