Don't bind. Use a setter function for fldValue, then in that setter, call your logic to update the selected property.

I can't figure out the right way to do this. I would like to create a custom CheckBox that can accept a string value as a property. For example, if my model returns the string "apple" then <util:MyCustomCheckBox value="apple" fldValue="{model.myCustom.fld}" /> In my extended CheckBox code it looks at that fld and then decides whether to select the CheckBox or not. private function getBooleanValue():void{ if(value != fldValue){ selected = false; }else{ selected = true; } } My problem is with the binding. I can't seem to set it up properly so that when the fldValue property changes, the function will get called thus changing the selected property. I also tried to create a getter function "_booleanValue" and bind the selected property to that, but I ran into problems trying to bind getter functions. The whole binding thing makes my head spin so hopefully this is simple fix... Thanks, Kevin
