Hello Team,

In our eclipse RCP application, I found that randomly eclipse properties page disappears and we are not able to find the root cause of it.

--> Properties view only goes to normal after restart of eclipse :-(

Will be thankful if any of you can help us in finding the "root cause"/solution

If I look in the ErrorLog view, I see there is unhandled event loop exception

just for further info, I am putting the stack trace which I obtained form the exception in ErrorLog.

Additional information : we use Sphinx for generating editor and model management in our project.

In the below screenshot, i have added a call trace of various methods on click of a model element.
