Hi,

I want to use workflow to run an evl file. The EVL program uses four metamodels. One of the metamodels is the trace metamodel, which refer to source or target elements in the source/target metamodels. The type of these references are EObject.
When I use the workflow to run EVL, the below error is appeared.

EXCEPTION: Property 'name' not found in object org.eclipse.emf.ecore.impl.DynamicEObjectImpl@a20537 [eClass: org.eclipse.emf.ecore.impl.EClassImpl@14bf9bc [name: Family] [instanceClassName: null] [abstract: false, interface: false]]

The minimal example is attached.

Bests,
Leila.

Hi Leila,

The ANT file in the attached project runs without errors on my end. Could you please try it in a clean workspace to ensure that this is not a side-effect of e.g. registration of multiple metamodels with the same nsURI.

Cheers,
Dimitris

When I want to run the ant file, from the External Tools configurations window I set the JRE>Run in the same JRE as the workspace. Any other config is needed?

Hi Leila,

Not really. Can you please give this a try with the latest Epsilon stable distribution from [1] and let me know how it goes?

Cheers,
Dimitris

Hi Leila,

Adding expand="true" to your Families2Persons epsilon.emf.loadModel should do the trick.

Cheers,
Dimitris
