    List Component doesnt update dynamically?

      Hi everyone,

      Im very new at flash, only been writing stuff for a couple weeks, so maybe there is a simple solution. I have a List component that i use, and it doesnt seem to update its labels dynamically when i change an object in the dataprovider. The code goes like this:

      I use a dataprodiver.

      var dp:DataProvider = new DataProvider();
      mylist.dataProvider = dp;

      var myObj:testObj = new testObj("name");

      mylist.labelFunction = setLabel;

      function setLabel(Obj:Object):String{
      return Obj.name;

      then if I change the object name, it doesnt update the label.

      myObj.name = "test 2";

      I have even dispatched an event in the in myObj and added a listener so
      I can explicitly make the List update label, but I cant find any
      function call to make it do that. Driving me insane :)

      Please let me know if youve experienced that same., TIA

          Can someone at least let me know if its impossible to do? If it is, Ill look for another way to do listboxes.

            I haven't played with as3 yet, so I'm thinking in as2 - and I see some differences (the dataprovider stuff looks good). But it does also mean that is advice may be way off track. Please ignore this post if it looks that way.

            I have no idea what you're doing here, I assume testObj is a class you created:

            var myObj:testObj = new testObj("name");

            if not, then just use:

            var myObj:Object = {name:"nameless"}

            Otherwise... name must be a property accessible from your testObj instance (ie. defined in your testObj class as public ) to return a value from labelFunction. If your class of testObj has a name property then what is it initialised to? the value "name"? Without knowing whether testObj instances have a name property I can't understand how it would work. But like I said... I don't know as3 and maybe I'm missing something.
