Hi,

I am trying to assign the owner of a 'Statemachine' element, which is of type "Element", into an ereference of a Class in my own ecore model. Please find the attached screenshots of the properties view of 'owner' object in uml.ecore model and in my metamodel. I am getting a runtime exception "Internal error: java.lang.IllegalArgumentException: The feature 'owner' is not a valid changeable feature". What am I doing wrong here?

Thanks

Hello,

I think you should set the attribute "Changeable" to true.
