SEVERE: /ide?session_id=6178:
org.eclipse.swt.SWTException: Invalid thread access

at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:718)
at org.eclipse.swt.widgets.Control.getBounds(Control.java:692)
at
....
Is this a bug?
Mike

Hi,
I think this could be solved in CVS-Head (see Bug #232289).
Ciao

Hi,
please provide a little more information about you problem, because the
question in this thread is about understanding the exception handling
mechanism of RAP. Mike has thrown deliberately an NPE, so I don't think
that this is really what you are doing. Do you have any stacktraces
available for example?
Ciao

I have a search box, and it works a while and after it returns this
exception.
I search in a database and if the first thing I do when I start the app
is
the search it works, but if I do anything else and then I try to search
it
crashes.

Hm,
that's strange. Currently I don't have a clue how this could happen
without any background threads involved. Is it possible for you to
extract a little demo plug-in that simulates the search and reproduces
the problem? If so you could post the plug-in at this newsgroup, and we
could do a further investigation.
Ciao
