I have created a new Custom Editor extending the Diagram Editor
When I open the workspace and create diagram /open existing diagram.
Everything works , but when I close and reopen the same diagram , and try to create new elements I get this error.
When I debugged I found out that the DefaultEditDomain is somehow not getting the latest one, and using the first opened diagram's DefaultEditDomain.
DefaultEditDomain domain = getDiagramContainer().getEditDomain();

I found the mistake in my code , I was using
private static IToolBehaviorProvider[] toolBehaviorProviders;
instead of
private IToolBehaviorProvider[] toolBehaviorProviders;
in CustomDiagramTypeProvider extends AbstractDiagramTypeProvider implements IDiagramTypeProvider {}
.
Resolved.
