OCL expression syntax check in Xtext editor
All expressions that embed OCL (Theta join, keep calculated attribute)are currently not checked for valid OCL syntax and correct return type. This should be done using the Eclipse OCLHelper in a way similar to the generation of QVT code for keep calculated reference. The result should be provided in the Xtext Editor as a hint for the user.
Closed issue due to 'ModelJoin' project discontinuation.
