Can you use CellTable#setVisibleRangeAndClearData() to clear the current data and request the new data from the database? http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/view/client/HasData.html#setVisibleRangeAndClearData(com.google.gwt.view.client.Range, boolean) <http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/view/client/HasData.html#setVisibleRangeAndClearData(com.google.gwt.view.client.Range, boolean)> Thanks, John LaBanca [email protected]
