Description Yvan Lussaud CLA 2012-02-01 10:59:52 EST 
Hi,

  I have a metamodel located in the generator plug-in (in the workspace). The source code is generated. This metamodel has a dependence to an other metamodel deployed as plug-in.

  The compiler seems to load two different EClasses for the same EClass :

        <letVariable name="var">
          <eType xsi:type="ecore:EClass" href="http://snipe#//Smurf"/>
          <initExpression xsi:type="ocl.ecore:PropertyCallExp">
            <eType xsi:type="ecore:EClass" href="platform:/plugin/snipe.ecore#//Smurf"/>

As a workaround I will deploy the first metamodel.

regards,
Yvan.

I believe this issue is a duplicate of this resolved bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=362985

The problem in the other bug was ultimately an incompatibility between a query defined on EClass on a module using a metamodel depending on Ecore.

The module had two ns URI, the one from the metamodel (located in the workspace) depending on Ecore and http://www.eclipse.org/emf/2002/Ecore. So the query taking an EClass as a parameter was using the type http://www.eclipse.org/emf/2002/Ecore#//EClass while the metamodel had a dependency to platform:/plugin/org.eclipse.emf.ecore/model/Ecore.ecore#//EClass.

A fix has been contributed on HEAD and R3_2_maintenance, it will be available in Acceleo 3.2.1 and 3.3.0.
