[flexcoders] Combobox in DataGrid

[kumarmenon]

Hi 

Is there anyway i can show a DataGrid cell with Combobox with arrow shown all 
the time..Currently the way i have it setup is as following. And it does not 
show the Combobox..

<mx:DataGridColumn id="xxx"
                                                           headerText="xxx"

                                                           dataField="xxx"
                                                           editorDataField="xxx"
                                                         
itemEditor="com.travelers.pi.ria.controls.MyComboBox">
</mx:DataGridColumn>
