[jboss-user] [JBoss Seam] - Re: How to correctly use @DataModel's rowAvailable?

[avbentem]

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.
