Hi,
This is the generic problem we face with itemRenderers , actully
itemRenderes recycle with each refresh, so use custom renderer instead
of mx.controls,checkbox, and set its selected property as required
using
override public function set data(value:object):void
{
super.data = value;
if(data != null){
check.selected = chkValue;//variable name
}
}
set chkValue on the click of check box
