Grouping and pagination in grids

Hi,

SmartGwt Power build 2040803

As far as I understand, grouping in ListGrids require the client to retrieve all data from the server.

This is fine. However, when testing this, it appears as if the grid is retrieving the server data in page sizes of 75.

Is there any way to make the grid retrieve all data in one single fetch when grouping while keeping the page size of 75 for ordinary fetches?

Regards
