Exception: org.eclipse.swt.SWTException: Widget is disposed [message #1735167]

Hi,
Im trying to run my test suite and I get an exception after the 1st test is run.
I tested on RCPTT 2.0.2, 2.1.0 p2 install/2.0.2, 2.1.0 RCP Testing Tool IDE and see the same exception consistently.

Has anyone seen this error/issue before? I think this is a serious bug.

Any help is appreciated guys! Thanks in advance!

I have come across this once before, it seems that sometimes previous tests that executed a call on a particular widget can leave that call stuck in RAM. The easiest way to solve this is to restart your AUT at the start of your test. To do so add the following code to the beginning of your ecl script:

restart-aut
wait-until-eclipse-is-ready

This should fix the problem.
Note. If you are relying on contexts to skip things like welcome pages it might be more prudent to put it at the end of the previous test instead.
Hope this helps.

Probably depend from your context file.
Try to re-create it.
