The internals are not changing the value property. They are in fact changing the 'selected' property and you are calling 'get value' in your alert, the value of which which is always calculated based on the current 'selected' property value. The binding event is fired only when the value property is changed by something else. And in your case, it is never changed and hence binding never occurs. - venkat http://www.venkatj.com --- In [email protected], Sherif Abdou <[EMAIL PROTECTED]> wrote: > > Doesnt he need ti dispatch an Event so it works?
