This seems relate to the fix for bug 221392: IUndoManager undoManager = getUndoManager(); if (undoManager instanceof IUndoManagerExtension) { IUndoManagerExtension undoManagerExt = (IUndoManagerExtension) undoManager; _undoAction = new UndoActionHandler(_site, undoManagerExt.getUndoContext()); fGlobalActions.put(ITextEditorActionConstants.UNDO, _undoAction); } In this case, _site is null, and it cause the NPE on UndoActinHandler. Radoslav, could you please take a look at it? Thanks.
I've just been notified that this is a critical issue. Please investigate. Thanks!
I have modified initializeActions() to add the undo action only if _site is not null. So in this particular case the Undo action will be unavailable.
Thanks Rado!
Works now! Thanks everyone!
