Hi Rafael, thank you for offering me your solution. But in the meantime I found a very simple solution:
The application has to set the new range *before* a call to updateRowCount is made! The first thing I do right after the data source (chat room) changed is to load the new row count. But *before* passing this new row count to the data provider (which would trigger an onRangeChange event then), I set the range myself to a valid interval. Finally, *after* this, I call updateRowCount. Pseudocode: void onSelectChatRoom:() { loadNewRowCount (); } void onLoadNewRowCount (int cnt) { Range r = getLastPageRangeForCurrentRoom(cnt); tbl.setVisibleRangeAndClearData (r,true); // triggers one onRangeChange event pvd.updateRowCount (cnt); // does not trigger a second onRangeChange event anymore! } HTH Magnus -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
