What's the point of Display.findDisplay(Thread) ? [message #823892]

I have a reference to the UIThread, if I call Display.findDisplay(Thread), I get an exception saying no context is available. I can't call UICallback.runNonUIThreadWithFakeContext to run in a fake context because I don't have the display yet...

I've checked the cvs history and this would have worked before rev 1.116 of Display.java.

"Applied patch from bug 337787: [Refactoring]: remove singletons and static fields in
RWT"

My problem is I have a background thread that goes through the open sessions and does some clean up. Its got access to the ui thread as it is stored in the session. There is no public way to get a Display object from a UIThread.

Hi Chris,
if your code works before the mentioned revision 1.116 of the Display
and not after it's probably a bug. Could you open a bugzilla with a
snippet to reproduce it?
Best,
Ivan
