Fixed in HEAD in DeferredMethodWrapper$1.run() CallHierarchyViewPart.dispose().
(In reply to comment #1) > Fixed in HEAD in > > DeferredMethodWrapper$1.run() > CallHierarchyViewPart.dispose(). This fix is working but it's not ideal. 1. we normally don't dispose PageBook since that's not needed 2. DeferredMethodWrapper$1.run() can check whether the viewer's control is disposed and hence there's no new method needed on the part Adjusted code in HEAD accordingly.
