QE, can you please confirm whether a render target of _tableId@rows[rowKeyVar]_ works as a
render target, triggering the render of a table row in an ajax request?

 @ManagedBean(name="testBean")
 @SessionScoped
 public class TestBean {  
     private static String [][] initdata =
{{"test"},{null},{null},{null},{null}};   

     private List<String[]> data = Arrays.asList(initdata);   

     public List<String[]> getData() {  
         return data;  
     }
 }
 {code}
 does not work: table cell getting not updated, when input field content is changed.
Relacing render="cell" with render="input" fixes the problem. 
 See also the forum thread.
 Similar code works with RF3.3.3
