I am sure this is easy and I am just missing something, but I want to
bind my integer attribute to an NSTextField. The data is displayed
correctly, but after I update the value in the text field and try to
save the changes back to my model. I get an error saying that the
update failed trying to set the integer value to a string value.
I have been searching for a while and I think I need to use a number
formatter, but it would seem that there is an easier way to do this.
On a side note, what is the best way to make sure only numbers are
typed into the text field?
Thanks in advance
