   Preondition Violations

   Type org.eclipse.swt.graphics.Image of variable rightGradient does not match with type java.util.List<org.eclipse.emf.ecore.EStructuralFeature> of variable result
   - Make classes org.eclipse.swt.graphics.Image and java.util.List extend a common superclass

   Preondition Violations
