Dear Epsilon Community members,
I need some urgent help from you regarding applying the EVL constraints on the metamodel I have prepared. I have three inter connected
> meta-models 1) featuremodel, 2) implementationmodel and 3)runtimerequiredactivation. all three models are under one DSL called
DemoDsl.
I am trying to compare the featuremodel attributes with
runtimerequiredactivation attributes. I am unable to do so. I uploaded the following files 1) DEMODSL.emf file from which you can generate the DSL
metamodel, editors etc, 2)demo.DemoDsl which is one instance of the DEMODSL
and RTA-PatternAnalysis.evl.

Please generate the code,editors and tests in the development environment.
After applying the evl constraints on the demo.DemoDsl instance i am
getting the following error

Property 'sources' not found in object
org.eclipse.epsilon.eol.types.EolModelElementType@703529
D:\eclipse-Indigo\runtime-New_configuration\AOPDep.implementation\RTA-PatternAnalysis.evl@24:43)

Many thanks,
saad

Hi Saad,

I've noticed that your metamodel makes use of nested packages - which are a common source of grief (see [1]). Could you please try to flatten your metamodel or split it across different files with 1 top EPackage each and see if this fixes the problem?

Cheers,
Dimitris
