[Trinidad] Modal Dialog window in IE 8 Tabs

[Christian Beutenmüller]

Hi folks,

I've come across an issue using modal dialogs and IE 8. I don't if it's
an actual bug or just a dumb programmer, so I ask here first, before
spamming the Jira.

Setup: Trinidad 1.0.11, MyFaces 1.1.5, Faceclets
Browser: IE 8

Application works fine.

I try to open a modal dialog using:

facesConfig:
..
<navigation-case>
   <from-outcome>dialog:showAssignmentTree</from-outcome>
   <to-view-id>/pages/assignmenttree.xhtml</to-view-id>  </navigation-case>
..

launchPopup.xhtml:

<tr:commandButton                                        styleClass="button"    
                                
text="#{i18n['assignment.button.change-assignment']}"                           
windowWidth="640"
windowHeight="550"
partialSubmit="true"
useWindow="true"
returnListener="#{myForm.fireAssignmentReturned}"
launchListener="#{myForm.fireAssignmentLaunched}"
partialTriggers="assignmentTable"
action="#{myForm.doLaunchDialog}"
                                                                        
                                />                      

FormBean:
public MyFormBean {
String doLaunchDialog() {
return "dialog:showAssignmentTree";
}

public void fireAssignmentLaunched(LaunchEvent evt) {
//some calls to:
// evt.getDialogParameters().put();
}

Now my Problem:
If I set the IE 8 to "Open all popups as tabs", it opens a background
tab and "freezes" while diplaying the greyed out main window.

If I take a look at the current 1.2.x demo at irian.at, modal popups in
tabs work like a charm.

Is this a known issue? Have I done something wrong or has anyone a idea
how to fix this?

Any ideas or help is apreciated,
Christian
