Hi. I've got a popup button with a bunch of GMT offsets configured in
IB, and bound via selectedTag to an NSArrayController's selection's
gmtOffset property. Each item in the menu has a tag value set. The
binding is properly setting the values of the selection, even if
multiply selected, and the popup properly updates as the selection
changes.
I'd like to display some custom text in that popup when there are
multiple values in the selection. But I'm pretty sure I need to
specify a tag value in the "Multiple Values Placeholder" field in IB
(under the selectedTag binding of the NSPopupButton), but I don't want
to create an item in the popup menu just for this value; that would
imply (and allow) the user could select it, which wouldn't make sense.
What's the right way to do this?
TIA,

Rick
