This feels more like a programming error. Does the error only occur when a specific view gets opened? Brian, put a conditional breakpoint on org.eclipse.swt.widgets.Control#setLayoutData(Object) with condition layoutData instanceof org.eclipse.ui.internal.WindowTrimProxy That should help track it down. (In reply to comment #2) > Brian, put a conditional breakpoint on > org.eclipse.swt.widgets.Control#setLayoutData(Object) with condition > > layoutData instanceof org.eclipse.ui.internal.WindowTrimProxy > > That should help track it down. Brian, did you get a chance to try this? This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie. The class WindowTrimProxy was deleted in 2016 with #206fd25b7739e1598640e96988bdb8ab51f26aa9. This bug is obsolete now. |
