--------------------------------------
Hi Wouter,
thanks for the reply. For now I found a work-around:
Removing all Entity Stereotypes in my model.
I found in the source that it only tries to cast it when there is an Entity
stereotype attached. I am just starting to understandabout how androMDA builds
its internal datastructures. Therefore I have only a few ideas. A fast bugfix
could be to check for being an instance of ModelElementFacade instead only
MetafacadeBase.
I remember another ClassCastException in EntityMetaFacade where the following
code fails:
if (superClass.hasStereotype(UMLProfile.STEREOTYPE_ENTITY))
{
Entity facade = (Entity)superClass;
identifiers.addAll(facade.getIdentifiers(follow));
}
Here could fix the replacement of the
"superClass.hasStereotype(UMLProfile.STEREOTYPE_ENTITY)" through "superClass
instanceof Entity" the problem...
But for now the workaround is ok, because our main focus the next days/weeks is
on generating code for interfaces/value objects and XML. I will start to add
entity stereotypes on requirement again and then try to rebuild our application
several times. The hope is, that I will find the problem in the model that way.
BTW: AndroMDA works fine with Maven 1.1, at least for the small things we do
actually.
Regards,
Thomas
