@voddan A ListCellFragment is contained in a ListCell, and a ListCell is reused to display different items as you scroll through your list. For that reason, the itemProperty and corresponding "getter" in item is changed as the fragment is reused to display different items as well. When you initialize it, there is no item bound to it at all. That's the reason the item value is null in the constructor. For this use case I think it's much easier to use cellCache which gives you the item right away. To use cellCache you must make sure that you have a valid equals/hashCode impl in the Word class.
