Hi,

when I have two or more model files of my DSL (based on the Domainmodel example) and I copy an entity (which is referenced from other entities) from one file to another,
I get the following error:

I cannot find any of my classes in the stack and the error is shown in the editor inside a error dialog.
This is quite annoying but I have no idea where it comes from...

Any ideas on this?

Thanks,
Ingo

Are you doing anything with a JVM type which resides in the default package, perhaps?

Meinte, I don't know exactly what you mean, but could it have something to do with the inferred type of my moved element which doesn't find its association anymore (of course, I have moved...)?
But I would say that this is a bug in Xtext then?

Please file a bugzilla with instructions to reproduce the problem.

Thanks,
