Any idea for pt 1 below(if just need to bind the NSButton enable
property to TextField,
to be enabled only iff atleast single character in textfield else
disabled)?
Implement a method in your(nib) controller class, which will return
bool value, based on the characters availability in the text field.
Set the NSButton enabled properties as below:
1. Select the Bind check box
2. Select your controller from the Bind to: pop up
3. Mention your bool method name in the model key path
I didn't try this. hope it will work.

Hi All,
I tried and searched the list extensively for something which seems
simple but doesnt seem to work for me.
My nib has a simple textbox and a button,
1) I want to bind my button to be enabled only iff their is sometext
typed into the textbox
2) Ideally I want as soon as I start typing into textbox it should
call a validate method and replace the value of the allowed value.
So say input to Textbox is "123abc" and only "abc" is valid:-
1) Button enables as soon as something is typed into textbox
2) As you type 123 nothing appear only abc ie the valid input appear
in the textbox.
*Want to achieve this through bindings, not the textbox callbacks.
TIA,
Miç
