Show promt when loading data from server

[jackal]

Hi all,

I have a screen with a combo-box and a grid. I have a custom data source to retrieve data via a GWT RPC service to fill the two controls.

Can anybody to help me for displaying a loading promt when fetching data, and to be hidden when fetching data completed, which looks like RPCManager fetch data promt. How do I do that?

Thanks.
