OK,
I have solved the problem where the changed relationship would change
in all columns by changing the selectedObject binding from Controller
= selection to Controller = arrangedObjects.
Not sure i quite understand this as both quoted tutorials have the
detail set to Controller = selection, the only difference with the
tutorial is that the detail components are separate from the master
NSTableView where my detail components are in the same table.

Hi all,
I am trying to create a master detail view in one NSTableView, I have
two text field cells which are the master values and then two
NSPopUpButtons for the detail, which are bound to two different
lookup entities.
The two master fields have a attribute value binding to the master
entity and the two detail popups have
content bound to their controllers, contentValue bound to their
controllers and a specific attribute and selectedObject bound to the
master entity with selection and the model key path to the
relationship.
I can select the popup details ok, but if I leave the row the detail
popups go blank. Also if I have more than one row, selecting a
detail on one row changes the detail in all rows for that column.
I have been following the instructions at:

Many thanks for any pointers, Martin
