    DataModelSelection Problem

    recycle bin Newbie

      I am using SFSB and @DataModel to display a list of record. But when i press "edit" button to select a record to edit with @DataModelSelection. It always select first record in the list, not selected one. Does anyone know why?

       @DataModel
       private List<Record> entityList;
      
       @DataModelSelection
       private Record selectedEntity;
      


      In the JSP's DataTable

       <h:column>
       <h:commandButton value="Edit" action="#recordBean.select}">
       </h:commandButton>
       </h:column>

          You seem to be missing a { in your JSF

              I think @DataModelSelection only works when you use s:link ;).

                No, it quite definitely works without s:link

                  For me, It didn't work with s:link. But I make it work with commandButton... see

                  http://www.jboss.com/index.html?module=bb&op=viewtopic&t=88100

                  anyway, What about your entityList factory?. Can you post your entire bean, and your page? Perhaps, I can help you.

                  Regards.
