Thanks for your answer, I'll do just that.

the class keeps the "readyNewItem" property updated according to

for it to wait until the didEnd selector is called to return from
the -runNewItemSheet method. That way, "readyNewItem" will be
properly assigned and not nil.
Is there any way I can accomplish this while still allowing the
panel to work (IBActions etc.) but not return from the original
calling method? I'm drawing a blank here.
Thanks for any help.
You can't.
You need to refactor your code so that the code that needs to run
when the sheet is dismissed is triggered by the sheetDidEnd:...
method. You can't wait on a sheet completing then continue - the
design is simply not modelled around that approach. The only time
that will work is if you are running an application modal dialog,
but a sheet is not application modal.
I usually handle this by declaring an informal delegate protocol for
the controller class that handles the sheet, and setting the
delegate when I ask the controller to run the sheet. The controller
implements the sheetDidEnd: method, and if OK (or whatever) was
clicked it invokes the method on the delegate that I decided it
would invoke. Then the delegate (the original caller) performs the
relevant task.
