ArcGIS Server for Flex

Hello Guys,

I've a question about arcgis server flex api.
Is it possible to display a datepicker in widget by using a expression value similar to a userlist displays a combobox?
I don't want to have the control in the mxml instead only show it as part of the expression builder on a eSearch widget.
Could you guys help me on this?

Thank You,
Keith Martyn
