Bug 320672 - [WorkbenchParts] [Compatibility] SWTException whenY20170216-1515Y20170216-1450I20170216-2000
activating an editor with stale content This is the second part of the fix for bug 320672, the first one is covered by bug 511873. Remember if we are in the middle of the focus state change. During this operation we should not attempt to call updatePartControl() from sanityCheckState() (which is called on part activation) because it can dispose widgets we are currently setting focus to. In theory, this can happen from other protected methods here too, but I'm trying to keep the patch as small as possible because this class is a base class for MANY other text editors.
