Subject: [flexcoders] Cannot
assign selected value from a radiobutton that was created dynamically.
I am creating radioButtons dynamically using an
array. When I try to
assign the selected value into a Text or TextArea
it doesn't work. It seems
that I am using addEventListener correctly since I
am able to see the
event.target.data in an Alert.
This application shows what I mean:
1. The radiobuttons are created out of an array.
2. When you click on any of them you get an Alert
showing the data you
have clicked. However, it doesn't change the text
of the TextArea.
Eventually I want to assign this value, to some
place else.
3. If you execute the same code
txtReceipt.text="Button" - by clicking on
the Button it does change the text.
the code below is runnable and shows the problem
...
Thanks ....
