Edit Widget that Would Auto-Increment the Unique ID

Hi there,

Does anyone know if there is an edit widget out there for ArcGIS Viewer for Flex that would create a new feature with the unique ID automatically incremented (from the last ID number) each time the user adds a new feature through the widget?

I currently use the Edit Widget in a map application, but it does not add a value for the unique ID column when the user adds a new feature.

Please advise.


Thanks,

Thanh
