I thought of that, but didn't try it. In the
meantime, I instead realized I could eliminate the
model object instance from the nib, and, set the
controller content in code
[dataSetController setContent:dataSet];
where dataSet is my model object (instantiated in code
instead of the nib). I don't know why this worked,
but setting the Controller content to the FileOwner in
the nib didn't work. Aren't they equivalent?
