Problem with onChange event

Hi,

I'm currently experiencing a problem with the onChange event when using an input type datefield.
e.g.
<cfinput type="datefield" name="date_txt" width="175" mask="dd/mm/yyyy" onFocus="date_txt.disabledDays = [0,6];" tabindex="1" style="text-align:left" onChange="checkDate();">

And then when I alert the date selected in function checkDate, I still get the old figure.
e.g.
public function checkDate():Void{
alert("Date selected: "+date_txt.text);
}

E.g. if the original date displayed is 05/05/2008 and I select another date (02/05/2008), then when the alert box appears, it still shows 05/05/2008.

Any idea on how to solve this issue?

Is it a bug with Flash forms?

Thanks and regards,
Yogesh Mahadnac
