Yes, it would be an external reference, but I'm not sure what your point is about it
being external. Local and External references aren't really treated much
differently.
You've hacked before JPAV.... what would it take? :)
I didn't say it's easy, just that it should be done. It's definitely too
difficult to explain in an e-mail. If you can't figure it out from similar past
changes made to metamodels (such as the recent changes to the XML Document metamodel),
then I hopefully will have some time next week to take a look.
The solution I have locally now would just have to tweak the get/set
methods on the virtual table.
But have you taken into account what happens when a materialized model gets deleted,
either from the workspace or the VDB?
As an aside, there might also be something we need to address regarding renames, for any
type of model, not just materialization models. Seems like if there is a corresponding
model in one or more VDBs, we ought to ask the user whether they want to rename the models
within those, too. Impact would be we'd need to create a new VDB instance for all
VDBs in the workspace during a rename to query their contents.
