[flexcoders] Dynamic combobox from JSON request

[timgerr]

Hello all, I have a Json request that I get from PHP backend.  I am
learning so I have created a dynamic list for a combo box.  The
problem is that when I press a button and it gets the data, I then go
to the combo box and I see 1 entry.  If I then select the combo box
again I then will see all the entries. Not sure how to have all the
entries show  the first time I select the combo box.  Here is my code:
<?xml version="1.0" encoding="utf-8"?>

                [Bindable]
                public var myList:Array = new Array();

                public function personJSON(event:ResultEvent):void
                {
                        var rawData:String = String(event.result);
                        var person:Object = JSON.decode(rawData);
                        trace(person[0].item1);
                        trace(person.length);

                                trace(person[x].item1);
                                myList.push(person[x].item1);
                        }
                        trace(myList.length);
                }
                public function clearArray():void
                {

                        cmboOne.text = 'Choose';
