"Document is null or not an object" after PDF from ModalWindow
--------------------------------------------------------------

                 Key: WICKET-1798
                 URL: https://issues.apache.org/jira/browse/WICKET-1798
             Project: Wicket
          Issue Type: Bug
          Components: wicket
    Affects Versions: 1.3.4
         Environment: Windows XPsp2, IE7 and Acrobat 8.1.2 (with "show PDF in 
browser" disabled)
            Reporter: Federico Fanton


I'm trying to have the browser open PDFs automatically (no "open or save" 
dialogs) and in a new window (either a browser window or the standalone PDF 
viewer).
So far I've been using this method:

IResourceStream stream = new ByteArrayResource("application/pdf", 
pdf.toByteArray()).getResourceStream();
RequestCycle.get().setRequestTarget(new ResourceStreamRequestTarget(stream));

Everything works fine with Firefox 2 (on Ubuntu and on XPsp2), and even on IE7 
most of the times, but if I try to open a PDF from a submit Button inside a 
ModalWindow, IE7 starts throwing "document is null or not an object" errors and 
basically Javascript stops working..

According to Companion.JS the stacktrace for the error is (most recent call 
first):
wicket-ajax.js:51
wicket-event.js:110
wicket-event.js:29
