It looks like diagram node’s show-in-source action handler doesn’t have a condition associated with it to see if there is source to be shown. We need something like OutlineNodeShowInSourceActionHandlerCondition for the content outline node show-in-source. 

If you have a diagram node that is not backed by an XmlResource, it will throw a CCE when you try to execute the action.
