What about something along these lines:
private function selectComboItem( cb : ComboBox, item : String, itemField :
String = null ) : int
{
var dp : ICollectionView = cb.dataProvider;
var i : uint = 0;
if ( itemField == null )
itemField = cb.labelField;
for each ( var dpi : Object in dp )
{
if ( dpi[ itemField ] == item )
{
cb.selectedIndex = i;
return i;
}
return -1;
}
Obviously this needs a lot more work to be 100% generic, since the dpi's can be
any kind of object, including primitives like String and XML in the case of
XMLList based data providers, where you will need to use something like (dpi as
XML).attribute( itemField )[0] to get the required item field for comparison.
