[flexcoders] Error 1150 when overriding protected function

[Amy]

I'm trying to do a quick and dirty extension of LegendItem to fix the 
fact that, since the UITextFields don't wordwrap, they don't respect 
the 100% width given to them by Legend.  When I try to override 
createChildren to get my fingers on the UITextField, I get a compiler 
error 1150: The protected attribute can only be used on class 
property definitions.

Here's my function:

override protected function createChildren():void{
                super.createChildren();
                for (var i:int=0;i<numChildren; i++){
                        var child:DisplayObject=getChildAt(i);
                        var txt:UITextField = child as UITextField;
                        if (!(txt==null)){
                                txt.wordWrap=true;
                                txt.invalidateSize();
                        }
                }
        }

There's something odd about this class, because usually when you 
start typing override protected function in a class, it has a whole 
list of functions you might be overriding.  But in this class, that 
doesn't happen.

If anyone has any ideas, I'd be very grateful.

Thanks;

Amy
