Hello,
I'm trying to use HUTN in order to define a SQL model, but when I save the
file I just get this error:
org.epsilon.hutn.exceptions.HutnGenerationException:
java.lang.NullPointerException

The URI of the metamodel I'm using is 'http:///SQLModel.ecore', from the
main package of the ecore file (it has child packages). First I thougth it
failed because of the chidren packages, but I managed to define a QVT
model and another I made for proofs (both with child packages).

My code where I specify de metamodel is just:
=================================================
@Spec{
MetaModel "sqmodel"{
nsUri = "http:///SQLModel.ecore"
}
}
=================================================

Do you know something about this error?

Thanks,
H├ęctor.
