[jboss-user] [JBoss Seam] - DataModelSelection always returns first row from h:dataTable

[dkane]

When I click "Remove" in any row of the table, removeSelectedPosition() is always being called for first row(entity). What is wrong ? 


XHTML : 

<h:dataTable value="#{cart.cartList}" var="item">
  |    <h:column>
  |       <f:facet name="header">Quantity</f:facet>
  |       <h:inputText value="#{item.quantity}" style="width: 30px;"/>
  |    </h:column>                        
  |    <h:column>
  |       <f:facet name="header">Item</f:facet>
  |         #{item.part.description}
  |    </h:column>                        
  |    <h:column>      
  |     <s:link id="cancel" value="Remove" action="#{cart.removeSelectedPosition}"/>
  |    </h:column>                        
  |    </h:dataTable> 


cart component : 

@Stateful
  | @Name("cart")
  | @Scope(ScopeType.SESSION)
  | @Restrict("#{identity.loggedIn}")
  | 
  | public class ShoppingCartBean implements ShoppingCart, Serializable 
  | {  
  |    private OrderCMP cartOrder = new OrderCMP();
  | 	
  |    @DataModelSelection
  |    private OrderPositionCMP selectedPosition;
  |    
  |    public void addPart(PartCMP part, int quantity)
  |    {	
  | 	cartOrder.addPosition(part, quantity);
  |    }
  |    
  |    public void addPart(PartCMP part)
  |    {
  | 	this.addPart(part,1);
  |    }
  |   
  |    public void removeSelectedPosition()
  |    {
  |        if (selectedPosition!=null) removePart(selectedPosition);
  |    }
  |    
  |     public void removePart(OrderPositionCMP orderPos)
  |     {		
  | 	cartOrder.removePosition(orderPos.getPart()); 
  |     }
  |     
  |     @DataModel
  |     public List<OrderPositionCMP> getCartList()
  |     {		
  | 	return(cartOrder.getOrderPositions());
  |     }
  |     
  |     public boolean getIsEmpty()
  |     {		
  | 	return(cartOrder.getOrderPositions().size()==0);
  |      }
  |      
  |      public int getTotalPositions()
  |      {		
  | 	return(cartOrder.getOrderPositions().size());
  |      }
  |      
  |      public void resetCart()
  |      {
  | 	cartOrder = new OrderCMP();
  |      }
  |      
  |      public OrderCMP getOrder()
  |      {
  | 	return(cartOrder);
  |      }
  | 
  |      @Destroy @Remove
  |      public void destroy()
  |      {		
  |      }
  | 
  | }
