ComboBox - Setting Selected Values from data

Question

I am running into a problem in Flex 3 that seems to be
different from Flex 2. Maybe someone can help.
I have a function for setting a combobox selected item for a
location for a value when the titlewindow completes loading. The
value is a prior value from a prior save. In other words to set the
combobox a value from a prior session.
The locations xml file is loaded from a remote object
oncreationcomplete of the titlewindow. The setselectedvalue
function worked perfectly in Flex 2 but now only works in Flex 2
after the titlewindow is loaded. We tested this by running the
setselectedvalue function from a button click after loading.
The dataprovider length is showing 0 in our debugging. After
titlewindow up on screen the length is showing correct ( 35 ) - in
this case. Our viewxmlobject function is showing no xml. Shows xml
correctly after up on screen.
I have set the creationpolicy to "all". That did not help
either.
Any suggestions? Anyone. This is killing me. Spent two days
now trying to get back to working state.
private function SetSelectedValue_cbLocation(): void {
var xLocID:String = eLocationID.text;
//viewXmlObject( cbLocation.dataProvider )
for (var i : int = 0; i < cbLocation.dataProvider.length
; i++) {
//Alert.show( cbLocation.dataProvider
.locid, 'Location DataProvider', Alert.OK);
if ( xLocID == cbLocation.dataProvider.locid ){
cbLocation.selectedIndex = i;
break;
The combobox has the dataprovider set at design time.
<components:is2ComboBox id="cbLocation" x="585" y="4"
width="196" dataProvider="{xmlLocations.Record}"
labelField="locname" dataField="locid"
change="changeLocation(event)" disabledColor="#004080" prompt="1.
Please select location"></components:is2ComboBox>

Answer 1

Hard to say without seeing the code. Is the application
opening a pop-up window (the title window)? If so, where is the
combo box located? In the main app or the titleWindow? What calls
the SetSelectedValue_cbLocation() function?
