Put your list in a ListDataProvider and set the cellTable as the display: ListDataProvider<Contact> dataProvider = new ListDataProvider<Contact>( CONTACTS); dataProvider.addDataDisplay(cellTable);
When you change the visible range of a CellTable, it clears its current data and fires a RangeChangeEvent. Something (like a ListDataProvider) has to be listening for the event and provide more data. In your case, you are pushing the initial data, but the CellTable is only retaining the data on the current page. When you change the page, the CellTable is waiting for a data provider to push more data into it.
