Duplicate of issue found with Global Bean wizard.
"That's an interesting bug you've discovered with not being able to cancel the wizard and not effect changes to the model after doing changes in the wizard. It seems to be a flaw in the Global Element framework at the moment because the SAP wizard has the same problem.
When we pass the XML element to the wizard, we're essentially giving it free reign to edit the in-memory model with no way to return to the initial state. I'm not quite sure how to remedy that at this point."
Found a solution for the Bean wizard, but needs to be investigated for SAP.
