I am working on a program where my data is handled via CoreData. I have been able to hook the individual attributes to a textfield, but for my purposes, it makes sense to display and edit the multiple attributes via a single textfield cell (think "date" "month" "year" instead handled as "date/month/year").

I have tried to make a NSFormatter subclass to handle this but haven't been able to get it to work properly. I have setup a similar formatter for a similar program that wasn't CoreData-based without a problem, so I'm wondering if there is something I am missing...

So basically, the behaviour works fine at first. Data is displayed properly, but when I am editing a cell in the textfield, all the instances in the textfield begin to reset to default values (even those not being edited) and then the program quickly crashes.

Any help/suggestions are greatly appreciated.
