Hi Bryan,

the solution is to use NSSet... which is fairly easy in IB:

Bind StudentsArrayController "ContentSet" to DepartmentArrayController.selection.student (where student is the relationship). Now you can bind your student table to StudentAC.arrangedObjects ...

I wrote this without looking into my own code, so if I missed anything important, please call back!

I have created two models both of which have inverse relationships to the other.

"Department" has a relationship "students" which is a
to-many-relationship to "Student". Student has a relationship
"departments" which is a to-many relationship to "Department"


My goal is to have two tables, one that shows all the departments and the other one that shows all students for that department.

In my GUI, I have an NSTableColumn setup so that it displays all the
departments in the system. This is setup to the array controller
Departments and works nicely.

The "Department" drop down is not working very nice. My assumption is
that I should be doing the following:

1) Have the "Students" NSTableColumn bind to the department array controller.
2) Put the controller key to "arrangedObjects"
3) Put the model key path to "students.student.firstName"


This doesn't seem to work. Can anyone provide any help on this?

Regards,
Bryan
