So, I presume you'd want ERXModelGroup there. The above was not in
Application.java I presume. When asking for a objects for a specific
entity, has done one use the usual utilities to call on the specific
model?
ie.. NSArray items = EOUtilities.objectsForEntityNamed (new
EOEditingContext(), "Item");
I guess I'm only missing the link between auto-loaded models and the
above style call, which I did with this:
admitModel = ERXModelGroup.defaultGroup().modelNamed("admit");
admitArchModel = ERXModelGroup.defaultGroup().modelNamed("admitarch");
Does it just look for an Item across both models?
