The OCL and QVT editors have multiple levels of manually defined Ecore
metamodels and so I have seen this error many times.
Xtext 2.0 had a single unhelpful error message in this area against
which I identified many distinct causes in
From my experience, Xtext was generally correct but unhelpful in
explaining the problem. The messages are now much better.
If you can't spot your error, switch to an auto-generated Ecore
meta-model so that you can see what Xtext wants. Then raise a bug about
the inadequate diagnostic case.
