Description Remy Suen

I had a view up (don't really remember which one) and closed it right after startup. Moments later I got an error dialog for this problem.

Caused by: java.lang.IllegalStateException: Need an underlying widget to be able to set the input.(Has the widget been disposed?)
	at org.eclipse.jface.viewers.StructuredViewer.setInput(StructuredViewer.java:1681)
	at org.eclipse.emf.facet.common.ui.internal.views.AbstractTreeView$3.run(AbstractTreeView.java:137)

Hello,

Which view causes this problem ?

Sorry, I don't remember.

Asynchronous messages can always be run after a widget has been disposed so I suggest some checks get added.
