Hi,

I have a class called Ontology it has a reference to a class called OntologyDescription.

I want to have a constraint saying that Ontology can only have exactly 1 OntologyDescription.

in the gmfmap I already added
Audit Container
- Audit Rule
- - Constraint
self.ontologyDescription->size()=1
- - Domain Element Target Ontology

in the gmfgen I already set the Validation Decorator and Validation Enabled to true. and then regenerated the diagram. But when I run the diagram, the validation didnt say anything about not having any OntologyDescription.

Any idea where should i look?

Hi,

did you follow all steps from https://wiki.eclipse.org/Graphical_Modeling_Framework/Tutorial/Part_2#Validation ?

You could also use Epsilon EVL or OCLinEcore. It is important to select Validate from the edit menu in order to run the validation. You could also modify the code generation templates to invoke the validate action on save of the diagram.
