I use AsyncDataProvider, but that one doesn't have a refresh()
method. I made an issue:

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.
