dwt 2 updated to revision 70, the app still not work
1. right click on tree node A, popup a contextmenu
2. right click on tree node B, popup a contextmenu
3. right click on tree node A, the contenextmenu is not shown
the issue maybe releated to ActionContributionItem.updateImages the exception from sample code:
