  | <si:convertEntity entityClass="com.ripuk.model.MediaHardDisk" />
  | </tr:selectOneChoice>  


EJB

@Name("orderStorageBean")
  | @Stateful
  | public class OrderStorageBeanHome implements OrderStorageBean, Serializable {
  | 
  |   @SuppressWarnings("unused")  //seam handled outjection
  |   @DataModel
  |   private List<MediaHardDisk> hardDisks;
  | 
  | ...
  | }


Any pointers on what this might be?

Thanks for your help so far,

Chris.
