I am following the "getting started" document on EMFForms on my custom data model. I have references to other ecore files in my model and the root class is extending a class in the reference ecore model.
While using the new view model wizard, I see the super class for the selected root class is displayed as null (attached the screenshot). I can generate the view model with default controls, but the view editor preview is not working and reports a NPE (copied below).
Could this be because of the referenced super class? Operation Reflection is disabled on the reference super class model, could this be causing an issue?
Thanks,
Roza
