Hello Cayla,

I do not think so. I think aboutToBeShown()/aboutToBeHidden() are UI-specific 
methods reflecting UI component visibility.
Yu can check if "public void setInput(IWorkbenchPart part, ISelection selection)" 
method is called on any selection changes. If not then you listen for the 
central selection events available in a workbench.

Once you reproduce this problem just get an exception from the log â it can 
contains some information about the actual reason of the problem.

Then you have to check if widget is disposed during notification processing.
