-- A modal dialog shell has a Text widget
-- ModifyListener is attached to the Text widget,
-- the modifyText sometimes gets called when the text widget is already disposed.

I don't have a concrete procedure of reproduction, but I think by typing quickly into the text and pressing ESC (which disposes the shell) you will see the problem.

Please advise, on how to debug this issue.
Thank you.

Hi,

there are some rare cases where events are processed in the wrong order
on the server. This will be fixed when the new protocol is extended to
the requests (currently its only used for responses).

I'm not sure if this is the cause for your problem, but I think it's
likely. However, feel free to open a bug for it.

Until it's fixed, you can work around the issue by wrapping the code in
your modify listener in a if( !text.isDisposed() ) condition.

Regards, Ralf
