          Hi,


          the documentation, the examples in the distro and the available book contain a lot of information. It will take a long time until somebody helps you at this forum, because you really should try there first.

              Hi,


              The errormessage is very clear:


              wrong number of arguments  and
              Could not invoke method by reflection: MobeeTopupController$$javassistseam9.retrieveAllTr(java.lang.String, java.lang.String)


              When you look at the code, the retrieveAllTr method has two Strings in its method, but in your page you are calling topUpTrList without arguments.
              The factory creates a shortcut, but to get the values it calls the method, so the Strings are needed.


              The best thing to do is to remove the tw Strings from the method and calculate or inject them in another part of the class. You didn't provide the whole code
              so its just guessing where the values of the Strings come from. I assume they are directly retrieved from the page and you have the set's and get's in your bean already.


              So basically :




              private String msisdn;
              private String instCode;
              
              // Sets and gets
              
              @Factory("topUpTrList") 
              public List<MobeeTopupTr> retrieveAllTr(){
                      return topUpTrList = airtimeDatabase.createQuery("from mobeeTopUpTr tr where tr.msisdn=:MSISDN and tr.instId=:INSTCODE")
                              .setParameter("MSISDN", msisdn).setParameter("INSTCODE", instCode).getResultList();
              }
              



              Hopefully this helps.

                Hi,


                additionally: Be careful  with the rendered attribute of the different elements. When there is NO result there will be nothing, so it can't be re-rendered either.
                Use a small trick with the seam-span or seam-div tags. They always render something, so it can be -re-rendered.

                  and i put the



                  <a:commandButtom .... 
                           .... 
                          reRender="searchTr"
                  </a:commandButton>
                  
                  
                  <s:span id="searchTr">
                     <h:dataTable...
                      ....
                      ....
                  </s:span>

                    Hi,


                    put an ajax-outputPanel around the s-span and gibve it an ID. Use that ID for the reRender.


                    So:




                    <a4j:outputPanel id="yourID"   >
                    <s:span id="searchTr">
                       <h:dataTable...
                        ....
                        ....
                    </s:span>
                    </a4j:outputPanel>
                    
                    and
                    
                    <a:commandButtom .... 
                             .... 
                            reRender="yourId"
                    </a:commandButton>
                    
                    



                    Besides this, make sure there is a result, so instead of returning with the list.



                    Query q = airtimeDatabase.createQuery("from mobeeTopUpTr tr where tr.msisdn=:MSISDN and tr.instId=:INSTCODE");
                    q.setParameter("MSISDN", msisdn);
                    q.setParameter("INSTCODE", instCode);
                    List<mobeeTopUpTr> result = q.getResultList();
                    log.info("I retrieved " + result.size() " entities");
                    return result;
                    



                    A lot more typing, but you can see what you're doing, Now you can see if the result gets you the data and i there is something for the databale to show.
