Stacktrace when shutting down the workbench
Thanks for the report Johan. I added a test to verify this issue has been fixed in HEAD by the recent fix for bug 200732 (see GraphViewerTests#testDisposalWithDragSource in org.eclipse.gef/test/org.eclipse.zest.tests). *** This bug has been marked as a duplicate of bug 200732 *** |
Build Identifier: 20100917-0705 I use the GraphViewer in an Eclipse view, if i add native DND support to the GraphViewer with addDragSupport( DND.DROP_MOVE, new Transfer[] { TextTransfer.getInstance() }, myDragListener )) It crashes if i shutdown the Workbench, DND itself works fine as long as the Workbench is running. The checkWidget() call in Widget.removeListener throws an NPE for the display when the controlListener is removed in DragSource.onDispose same with DropTarget. Regards Johan @see http://www.eclipse.org/forums/index.php?t=msg&goto=638209&S=ff54adcc25aa910bb032e24fcbd6ae9c Reproducible: Always Steps to Reproduce: 1. Create ViewPart with GraphViewer 2. Add DND support over addDragSupport (drag mode or transfer type doesn't matter) 3. Close the Workbench
