Quincey
Again thank you!
I did just that, 12 seconds before receiving your mail, so i'm glad
i'm not totaly lost:)
but the value still get's changed wrong, instead of changing the
relationship object it changes the display name of that object.
transactionType.name
I've tried to have the column value set to transactionType, but the I
get
*** -[NSManagedObject copyWithZone:]: unrecognized selector sent to
instance 0x155987b0
Grrr...
so i guess I should focus on trying to get it to change the
relationship object instead of it's display name.
is there a way to do that with bindings, or will i have to do it
manually ?
Thank you !

the combo box is content bound to a array controller that manages
the items i want to choose from in the combo box. as content values
(transactionTypes) name.
Try this:
Set the column's "content" binding to the transaction types array
controller, controller key "arrangedObjects", model key blank or
"self".
Set the column's "contentValues" binding to the transaction types
array controller, controller key "arrangedObjects", model key
"field1".
Set the column's "value" binding to the transactions (not
transaction types) array controller, controller key
"arrangedObjects", model key "transactionType.field1".
Don't bind the combo box cell's bindings to anything -- that's done
automatically for you every time the cell is used.
