The Xtext editor should show an error if you assign a value to a not changeable reference. If changeable is false, the ecore model won't get a setter for that feature which leads to a runtime error in the generated editor.

Reproduce:
1. Create a new Xtext-Project from existing ecore
2. Set a class with a not changeable feature in the ecore
3. Assgin a value to that feature in your grammar
4. Generate editor, open it and try to assign the value
5. The error "The feature ... is not a valid changeable feature"


Should be:
The Xtext-Editor should show an error, if a value is assigned to a changeable = false attribute.
