I've been testing the report designer for a potential project and I found a problem where some rdl files loaded into the editor with the graphical display for the report shows just fine and others it is completely blank. Attached is a screenshot to demonstrate what I see in SSRS report builder and what I'm seeing in the WPF application. Some other more complicated reports seem to load just fine, but this simple one with just one table and other simple ones I've created and tested don't show anything in the graphical designer portion. Any ideas or suggestions would be most welcome.
