Ah, I see. I don't think you aren't getting anything. :) There's an inherent UI ambiguity in your approach, because there's no detectable difference between a text field that's empty to indicate "no change" and a text field that's empty to indicate "zero-length string". In iTunes, for example, when you're editing info for a multiple selection, there's a checkbox next to each field to disambiguate this. BUT, this only works because it's in a modal dialog -- simply dirtying a field doesn't take effect till you click Next or OK. I think you have two sub-problems: 1. Detect when the text field is really being edited. That probably means you can't bind the field through the array controller directly to your data model. Instead, bind it to an intermediate property in (say) your window controller, and add window controller logic to determine what that intermediate property represents, depending on the selection state of the array controller and the editing state of the text field. 2. Decide when to commit changes from the intermediate property to the data model. For example, perhaps if there are multiple values selected, you need to show an "Apply" button in the popup, to avoid making it too easy to for the user to do the wrong thing. OTOH, if you're not happy with the generic multiple-values display anyway, maybe you should redesign the popup window and its behavior. NSArrayController is likely too much of a black box (and a blunt instrument) to be useful for a subtle UI. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
