[jboss-user] [JBoss Seam] - @DataModel does not create a component

Hi,
I have a SFSB:

  |             System.out.println("Uzman: id="+u.getId()+" ad="+u.getAd());
  |         }
  |     }
  |     
  |     public void refresh() {

  |

  |

  |         System.out.println(" acan="+istek.getAcan().getAdSoyad());
  |     }
  |     
  |     @End
  |     public void clear() {
  |         istek=null;
  |     }
  |     
  |     public List<Istek> getIsteklerList() {
  |         return isteklerList;
  |     }
  |     
  |     public void setIsteklerList(List<Istek> istekler) {
  |         this.isteklerList = istekler;
  |     }
  |     
  |     public List<Uzman> getUzmanlar() {
  |         return uzmanlar;
  |     }
  |     
  |     public void setUzmanlar(List<Uzman> uzmanlar) {
  |         this.uzmanlar = uzmanlar;
  |     }
  |     
  |     public void logSomething(){
  |         System.out.println("Trying to log something dummy and the logger is "+((logger==null)?"null":"not null"));
  |     }
  |     
  |     @Logger
  |     private Log logger;
  |     
  |     @Remove @Destroy
  |     public void destroy(){}
  |     
  | }
  | 

and I have the following in my page:

  |              
  |                     <h:dataTable var="istek" value="#{isteklerlist}">
  |                         <h:column>
  |                             <f:facet name="header">No</f:facet>
  |                             <s:link value="#{istek.id}" action="#{isteklerAction.setIstek(istek)}"/>
  |                         </h:column>
  |                         <h:column>
  |                             <f:facet name="header">Tarih</f:facet>
  |                             #{istek.acilis}
  |                         </h:column>
  |                         <h:column>
  |                             <f:facet name="header">Konu</f:facet>
  |                             #{istek.konu}
  |                         </h:column> 
  |                     </h:dataTable>
  | 
I cannot make the table to display the isteklerList. The table's header shows up but no data. I have verified to print that the data exists. I have a similar page in another app working but this one does not. In fact the DataModel component is not even created. I checked with the debug page to see that no component named "isteklerList" exists. 
What am I missing?
