If I select the new-style NSNumberFormatter, I don't see a "Zero" field in
Xcode/IB where I can enter that. Since it's working when I just create the
formatter in code, I'll just keep doing that.
What's really strange is that using the an almost identical project converted
from Xcode 3.2 to Xcode 4, but where my text fields were NOT then dragged
inside a new tab view, the same type of text fields hooked up to the same type
of formatter works perfectly, and shows "N/A" when my text field values are 0.
But in the project I'm working on, even if I delete the text fields and the
formatter and drag&drop new ones, as long as they're inside the tab view, I get
this behavior when the formatter is dragged&dropped in the xib, but no problems
when the formatter is created in code. No time to track down why any more,
though… got deadlines to meet! :-)
Thanks,
Howard

Hm, it may be that something else is at play here. I did make ONE change
when porting… I put my text fields inside a tab view. I wonder if maybe
there's a problem accessing the number formatter from a control inside a
tab view? All the connections *appear* to be there, and the call stack
does show that it's accessing an NSNumberFormatter (and there's only on in
my project). Need to run a test...
Ok… I just tested the same code using the OLD xib, WITHOUT the tab view,
and it works with no problems!
So… does anyone know if simply adding a (two-tab) tab view and dragging
existing objects on its pages causes any problems like this? Is there a
connection I've overlooked that I need to make once the objects are inside
that tab view?
Thanks,
