Description Tod Creasey

2006-01-25 16:18:54 EST

20050125 from a stack trace from Steve Northover

It looks like the isDisposed checks that we do for the progress indicator are not the right ones - it is possible to get updates when it is null (not yet created) as well as the progress monitor is created before the dialog is.

We should create the monitor after we create the widgets.

Here is a trace

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
