Actually, in Flex 1.5 you can set the selectedItem with: cb.selectedItem = cb.dataProvider.getItemAt(someValidIndex);
Why you would *want* to do that is another matter, since it's easier and probably much more efficient to just set the selectedIndex property: cb.selectedIndex = someValidIndex; If the dept column in your data is a numeric index into your combobox fields, just use that and you won't need to loop through the data. --- In [email protected], "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > I don't know why it ever worked, but you can't SET the selectedItem for > a ComboBox.
