Eclipse does not close until GEF editor is closed [message #757794]

Hi,

I've developed a GEF editor application. For some reason, when i click the eclipse IDE "close" button it does not actually close the IDE until i close my opened GEF editors or delete all figures from them.

After closing editors or deleting figures eclipse gets closed, throwing the following exception:

I know this won't be enough information to help me solve the issue, but i'm really lost. I don't know what to trace or whatever... Any clues?

Hi,

Kindly check whether you have done any paintFigure in your corresponding figure class. Sometimes it may execute your loop and it wont close. First of all identify when it happens and what are all the shapes available in the editor.

Thanks & Regards,
