Bug 49869 NPE showing Type Hierarchies history after layout change
Reported: 2004-01-12 14:15:55 | Status: resolved fixed

M6 - I retrieve the org.eclipse.swt project from cvs, though this should happen with any java project - select the project in the Package Explorer and press F4 to open a hierarchy view on it - drop down the hierarchy view's Previous Type Hierarchies tool item, it will show 1+ item(s), good - drop down the hierarchy view's dropdown (ie.- the down-pointing triangle in the toolbar) and select Layout -> Horizontal View Orientation - now try to drop down the Previous Type Hierarchies tool item and the attached exception will occur
