[flexcoders] how to auto select the first index in a sparks List control in flex4

[ew6014]

hi

i have a spark List control. it has a dataProvider that shows reply from 
twitter search.

i have created a function for change handler like this:

protected function list_changeHandler(event:IndexChangeEvent):void { ta.text = 
coverflow.selectedItem.title; }

so, whenever i select each of the items in the List i will see the 
message(ta.text) but now, instead of me manually clicking the first time, i 
want it to automatically click/select the first item and see the first 
message(ta.text)

how do i do it? ...
