Hi,
I have an NSTextField with a number formatter and an NSStepper in a view that
is used in an NSPopover. The values of both interface items are bound to an
ivar of the view controller via an object controller. Both the text field and
the stepper have a max value of 99999.
When I enter a value superior to that in the text field and tab out, or click
another field, an exception is raised. The backtrace is pasted below.
(Depending on my next action, or the way I exit the text field in the first
place, one or two alert views may show with the 'Value "x" is too large'
warning. The first alert has no title bar and can't be dismissed by clicking
the discard or ok buttons, the other alert is a proper window that can be
dismissed. I see these alerts also when the stepper is unbound, so the issue
looks to be only with the text field.
I'm not sure what, if anything, I'm doing wrong, and how to get this setup to
function properly. I've done this type of binding before, but never in a
popover window. Could it be a framework bug? Any ideas about what might be
wrong with the setup, and/or how to solve the issue?
