Bug 6970 Hierarchy tick marks out of sync
Build 20011211 - open org.eclipse.jface.actions.IAction - add method: public void setMenuCreator(IMenuCreator creator) { } - build - error mark shows up in task list and editor tab (method shouldn't have body), but not in hierarchy - make mod and save - hierarchy now shows tick - fix the problem and build - hierarchy still shows tick - make mod and save - hierarchy is now consistent
