In fact org.jboss.seam.jsf.ListDataModel delegates most of its functionality to
javax.faces.model.ListDataModel (link broken when I write this; see also the
API). The Seam code includes:
private void readObject(ObjectInputStream ois) throws IOException,
| ClassNotFoundException
| {
| this.setWrappedData( ois.readObject() );
| this.setRowIndex( ois.readInt() );
| }
I assume readObject() throws an exception when the ObjectInputStream is not
null but somehow emtpy, so I assume the readInt() could not yield -1 above, as
writeObject sets it using getRowIndex().
Still: could using the wrong scope somehow mess this up...? Note that Order
does implement serializable:
@Entity
| @Table(name="ORDERS")
| public class Order implements Serializable
Any thoughts welcome!
Arjan.
