Here is the relevant code from the component with the combobox:
[Bindable]
private var signalList:ArrayCollection = new
ArrayCollection();
public function setSignals(sig:ArrayCollection):void {
signalList = sig;
}
<mx:ComboBox dataProvider="{signalList}" selectedIndex="0"
toolTip="{signal.selectedItem.name}" change="selectSignal()"
color="#000000" id="signal" labelField="name"/>
And here is my Application actionscript code for populating signalList:
var arr:Array = archiveList.selectedItems;
for (var i:int=0; i<arr.length; i++) {
if (!signalList.contains(arr[i].name)) {
signalList.addItem(arr[i].name);
}
}
var sort:Sort = new Sort();
// Set the sort field (case-insensitive)
sort.fields = [new SortField(null,true)];
// Assign the Sort object to the view.
signalList.sort = sort;
// Apply the sort to the collection.
signalList.refresh();
