However when I instantiate an instance of the 'Heat' entity with :

however the entity name is @"Race" then the resultant pointer is
indeed of type Race.
Any thoughts on what could be going wrong ? The data model graph
looks perfectly correct, and there are no errors from the above
line at run time, just the wrong type of object being created
(though it does have the correct properties for a 'Heat' entity).
Did you remember to set the class on the Head entity in the data
model?
Yep - the classes for each entity in the data model are set to the
correct item. My data model is however behaving a little 'oddly' in
the graphical editor. It's a little difficult to describe (it seems a
little random) but selecting an entity in the list in the upper
right, and the selection on the graph and the property list for the
entity don't quite seem synchronized. Sometimes the property list
will be empty. Also if I tab to move between items (properties or
entities) the tab order seems a little non-sensical.
Is there a way to debug the loaded data model from within my app and
confirm that the "Heat" entity is really associated with a "Heat"
class etc. ?
