> I have a couple of lists with identification numbers. The lists contain entries that are displayed using a Grid. The page ShowEntries has a method onActivate(int id) to get the id from the request. A getEntries() method in that page returns the entries. When I load the page the first time via  /myapp/showentries/1 these methods are invoked:
> onActivate
> getEntries
> GridDataSource.getAvailableRows
> GridDataSource.prepare  (entries 0-19, objects per page is 20)
> GridDataSource.getAvailableRows (4x)
> GridDataSource.getRowValue (n times)
> on chaning to a different page of the table (the 3rd in this example)
> onActivate
> onActivate
> getEntries
> GridDataSource.getAvailableRows
> GridDataSource.prepare 40-59
> GridDataSource.getAvailableRows (4x)
> GridDataSource.getRowValue (n times)
> So far so good. Now I want to load a different list
> /myapp/showentries/2
> But the previous selected page of the table (and the sort column) is displayed instead of the first page.
> It would be nice to have a reset() method on the Grid to start the new request on the first page with a defined sort column.
