No, that should not work unless SDActionItem.platform is a reference to an item in the ComboBox dataProvider.

I have a combobox with a dataprovider of an arraycollection that is returned from a MySQL database. This is populated on creationcomplete. Once this arrayCollection is populated I make another call to get specific data. Part of this data is a field that corresponds to an item in the combobox. When the second call returns, all I do is: platformComboBox.selectedItem = SDActionItem.platform; SDActionItem is the DTO returned from the second call and platform is one of it's fields that correspond to an item in the combobox. This works every time and I do not have to loop through the data provider. Are you telling me that this should not work? --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > ComboBox.selectedItem will only work if you assign a *reference to an > item in the ComboBox dataProvider*.
