i reckon your the selectedIndicis is changing and therefore cannot
be relied upon within your for loop.
try this. (as a starting point)
private function removeSelected():void
{
var array1:Array = new Array();
for(var j:int;j < dgTest.selectedIndices.length; j++)
{
var num1:int = dgTest.selectedIndices[j];
array1.push(num1);
}
for(var i:int = 0; i < array1.length; i++)
{
acTest.removeItemAt(array1[i]);
}
}
