Create a variable to hold the current selection index
private var comboCurrentSelectedIndex:int = -1;
add a change event to the comboBox
<mx:ComboBox id="myComboBox" change="myComboBoxChanged()"/>
keep the selected index current
private function myComboBoxChanged():void
{
comboCurrentSelectedIndex = myComboBox.selectedIndex;
}
When the new data comes in, set the selectedIndex of the comboBox to
the saved index
myComboBox.selectedIndex = comboCurrentSelectedIndex;
