Re: Reload CellTable data

Thomas is correct on both accounts.  cellTable.setVisibleRangeAndClearData(cellTable.getVisibleRange(), true); will force a RangeChangeEvent to fire to the backend, but really your backend should be pushing the new data into the CellTable.  For example, if you use ListDataProvider you can call ListDataProvider#refresh() to push the data back into the views.

Maybe:
cellTable.setVisibleRangeAndClearData(cellTable.getVisibleRange(),
true);

http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/user/cellview/client/AbstractHasData.html#setVisibleRangeAndClearData(com.google.gwt.view.client.Range,
boolean)

But I think the expected use is to do it in your "model" rather than
the "view" (CellTable), where the "model" (or presenter, or whatever)
will fetch the data from the backend (maybe using getVisibleRange() to
filter it) and call setRowData() on the CellTable to update it.
