Question

I have two MXML component files and try to work with them as classes. One of them has a simple function:

GUIFriend.mxml

<mx:Script>
    <![CDATA[           
        public function createName(f:Friend) {
            return 'friendProfile: ' + f.uid;
        }
    ]]>
</mx:Script>

And the other tries to use it:

GUIFriendContainer.mxml

<mx:Script>
    <![CDATA[

        import GUIFriend;

        public function getFriendProfile(f:Friend):GUIFriend {
            var result:DisplayObject = getChildByName(GUIFriend.createName(f));
            if (result is GUIFriend) {
                return result;
            } else {
                // TODO: throw error
                return null;
            }
        }           
    ]]>
</mx:Script>

But in the line that references ‘createName’ function I get two errors:

1. Call to a possibly undefined method
   createName through a reference with
   static type Class. – (update) I forgot to make the method static.
2. Implicit coercion
   of a value with static type
   flash.display:DisplayObject to a
   possibly unrelated type GUIFriend.

But I see no rational reason for it. What’s wrong with my code?

Answer 1

For second problem, try

var result:DisplayObject = getChildByName(GUIFriend.createName(f)) as DisplayObject;

if you still have problems, temporarily type result as Object and put in a debug breakpoint to check what is really coming back from the getChildByName call.
