I have two screens for testing.
a) I set object values in screen 1 (for instance obj.value ="abc") and go to screen 2 b) I show the value in screen 2 with binding (for instance <mx:Label x="37" y="46" text="{obj.value}"/> and go to screen 1 it works fine when it excute first time.(from screen 1 to screen 2) Afater I change from screen 2 to screen 1,the binding value {obj.value} in screen 2 keep the previous value even if I change the object values in screen 1 (for instance obj.value ="xyz"). but the binding value {obj.value} should change to "xyz",do you know why this happen. Thanks for your help. Mark
