Hi,
i had a similar exception
calling a another shell from a wizard page. It also threw a WIDGET IS DISPOSED
exception. I found that there was a PropertyChangeListener active on may
calling shell. I removed the listener for that time and disposed the underlying
widget and everything works fine. Maybe this also works for you!
Best regards,
Christian

Betreff: RE: [gef-dev] Widget is
disposed exception in FigureCanvas during startup
Indeed it seems to be related to another
problem I got during startup. But I'm wondering because the workbench did start
fine after ignoring these exceptions (by patching the two property change
listeners for updating the scroll bars in FigureCanvas). ???

It is possible that another exception occurred and this
one was just cascading? Why is the Workbench disposing its Display? That
sounds like a startup error occurred prior to this.
DeferredUpdateManager
should *not* attempt a layout at this point because it would have been
disposed() already when the Canvas was disposed().

Hi!
