[flexcoders] Need help getting the groupName of a radio button in a function

[Mark]

I have 2 sets of radio buttons with 2 different group names.  I'm 
using them to do some filtering.  The function is pretty basic and 
will work with both groups but I need to know what group is calling 
the function.  Can someone please help me with the correct code to 
get the radioButtons groupName?



public function filterByBLine(evt:ItemClickEvent):void {
                trace (evt.currentTarget.groupName);
                if (evt.currentTarget.selectedValue == "All"){
                        projectArray.filterFunction = null;
                        projectArray.refresh();
                } else {
                        projectArray.filterFunction = DGFilter;
                        projectArray.refresh();
                }
            }


<mx:RadioButtonGroup id="businessLineRB" itemClick="filterByBLine
(event)"/>
