Yep... That's the problem. Julio, you can go into the class_temp Basic tab,
copy the class ID from there (and then change it). Then, replace the class
ID in your new ZClass. Note that this will break any new instances you
created (you may want to delete those first).

I think the howto mentioned below has the step-by-step procedure.
