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

Subject: [flexcoders] Re: Tilelist in Flex 2 - what to use instead of
getItemAt()?
Thanks for the suggestion. My new error is: value is not a function.
This comes up on this new line:
IList(myTiles.dataProvider).getItemAt(1).testFunction();
