Hello,

i created a custom renderer for an "path" attribute (textfield with button for file browser). The renderer is very similar to the example email custom renderer and the example tester too.

Is there a more generic solution for the tester? The tester depends on a special ecore model. So for every new model i have to adpat the tester.

public class EmailControlRendererTest implements ECPRendererTester {
 
    public int isApplicableForFeature(EStructuralFeature feature, VElement vElement, ViewModelContext context) {
        //here is my problem
        if (feature.equals(TaskPackage.eINSTANCE.getUser_Email())) {
            return 10;
        }
        return NOT_APPLICABLE;
    }

 
}

Thx

Hi,

you would need some kind of identification mechanism to mark "path"
attributes as such. Solutions could be:
- An annotation to the attribute
- The definition of a custom data type (in ecore)

second would also the advantage that you could validate the attribute.

Best regards

Jonas
