   Preondition Violations

   Type org.eclipse.emf.ecore.provider.EOperationItemProvider of variable eOperationItemProvider does not match with type org.eclipse.emf.common.util.EList<org.eclipse.emf.ecore.EOperation> of variable eOperations
   - Make classes org.eclipse.emf.ecore.provider.EOperationItemProvider and org.eclipse.emf.common.util.EList extend a common superclass
