Hello,
I am using UML as my metamodel for an XText grammar.
If my grammar is using Model, Package, Class and Operation, all is fine.
As soon as I use Property or Parameter, I get an error.
Part of the stack trace is below.
In that case I used Property.
There must be some property or some operation that is not supported and
that XText uses, but I don't know what to look for.
Thank you,
Lucian
