Description Laurent Delaigue CLA 2011-09-12 05:04:43 EDT 
Build Identifier: 3.2.0.v20110909-0837

I modified a template into a queyr, *without changing its name*.
It seems that all what's needed is not recompiled, and you get
ClassCastExceptions:
java.lang.ClassCastException: org.eclipse.acceleo.model.mtl.impl.spec.QuerySpec cannot be cast to org.eclipse.acceleo.model.mtl.Template

Reproducible: Always

Steps to Reproduce:
1. create a template
2. in another module, use this template
3. modify the template into a query : String with the same name
4. edit the module that depends on it
