Re: [flexcoders] Re: How to get the previously selected item in ComboBox on change?
why dont u do something like create a custom combo box, override the method
then just add the previous click to an array and once you have that just search
for the index before it or something along those lines

Hmm, completely bummed with this...I tried calling
e.preventDefault( );
e.stopImmediateProp agation() ; e.stopPropagation( ); on click event and
it won't cancel the default actions.
Seems like there's no other way but to extend ComboBox and override
the way it does changeHandler?
Thanks!

would it?
Thanks!

That is how I handle it.

Subject: [flexcoders] How to get the previously selected item in
ComboBox on change?
Hi!
I can't seem to get a reference to the previously selected item in
ComboBox on change. When the function executes on change, the
selectedItem has already become the newly selected item, I would like
to check on the previously selected. I checked on the docs and can't
seem to find any property that indicates previous item.
As always, thanks for the help!

It doesn't use click, it uses mouseDown/Up. If you get the change event from the dropdown in capture phase, you might see the old value in CB.
