sorry i didn't respond to your reply......slipped thru. continuing from Alex, and having a closer look at your original post ......flexcoders is so busy and sometimes i just look at the title and give an answer...i'll be a good boy and read the question properly next time.
what you actually want is to use the TileList.indexToItemRenderer() function. that gives u a reference to the itemrenderer eg. myTiles.indexToItemRenderer(1)["testFunction"](); //or TestComonent(myTiles.indexToItemRenderer(1)).testFunction(); //or var object1:TestComponent = myTiles.indexToItemRenderer(1) as TestComponent; object1.testFunction(); regards Bod --- In [EMAIL PROTECTED], "Alex Harui" <[EMAIL PROTECTED]> wrote: > > Erin, > > It looks like your array: > var arrTest:Array = [1,2,3,4]; > just contains numbers. > > IList(myTiles.dataProvider).getItemAt(1) should return 2; > > 2 is just a number so you it doesn't have a testFunction > > Did you intend to pass 2 into testFunction? > > That would be: > testFunction(IList(myTiles.dataProvider).getItemAt(1)); > > One good way to debug this is to start storing parts of the expression > in temporary variables. > > -Alex > > ________________________________ > > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On > Behalf Of erinwyher > Sent: Thursday, April 12, 2007 10:41 AM > To: [EMAIL PROTECTED] > Subject: [flexcoders] Re: Tilelist in Flex 2 - what to use instead of > getItemAt()? > > > > Thanks for the suggestion.
