[baseten-users] Using relationships with binding

Hi

I am beginning learning BaseTen and having difficulties with  
relationship and binding.
I have successfully built and run the CarLot and Stickies exemples.  
These examples don't use entities relationship.

Now I  try to build a BaseTen version of the simple Hillegass  
Department-Emloyee  example (3rd Edtion - Chapter 30).

The first problem  was with one-to-many relationship field and NULL  
value. I  manually edited the table to allow the relationship field to  
accept NULL.
But now my second problem is about using relationship with binding.

Is it correct with BX to use Array Controllers for the ManagerPopUP,  
EmployeeList (Department View) and DeptPopUp (Employee View) ?
Is It ok for these controllers  to be in "Entity mode" with  
"Automatically Prepare Content ?
What is the correct binding for these controllers ?
What is the correct key path for a relationship ? (trying the Data  
Model name and the "other table" name don't work).

Probably I am confused between Core Data and BX usage of relationship  
and Binding.

Is there available simple BX Xcode examples using relationship (using  
binding and using coding) ?

Thanks
