      i am kind of getting errors with each step i move forward with seam.

      I am having a jsf page manualTags.jsp, SLSB ManualTagService.java and an entity bean ManualTag.

      The manualTags.jsp has a search criteria and a seach button, on clicking that should retirve the result in the datatable on the same page.

      The problem i am facing is i can get the datatable on the page if i remove the code for search button, but when i try to go as per the business
      that is click search button and then render datatable its giving me wierd errors.


      2008-05-15 17:43:19,048 ERROR
      javax.servlet.ServletException: #{manualTagService.getAl\}: javax.ejb.EJBTransactionRolledbackException: java.util.ArrayList
      at javax.faces.webapp.FacesServlet.service(FacesServlet.java:256

      I have no clue where exactly the problem is, i have tried various combinations of the code.


      The code i am using is as follows.
      The jsp page has
                 





      
<h:commandButton value="Search" action="#{manualTagService.getAll}" />

<h:dataTable value="#{ManualTags}" rendered ="#{manualTagService.renderTable}"


The SLSB code

@Stateless

@Scope(ScopeType.SESSION)

@Name("manualTagService")

@Interceptors(SeamInterceptor.class)

public class ManualTagServiceBean implements ManualTagService, Serializable {

@Out

     @In (create = true, required=false)

     private ManualTag manualTag;


     

     @DataModel

     @Out(required=false)

     private List<ManualTag> ManualTags;

     

@Factory("ManualTags")

     public void findManualTags() {

          System.out.println("am i coming here befopre the query *****"+ this.manualTag.getLocation());

          

          ManualTags =  (List)manager.createQuery("from ManualTag mt where mt.entryLocationId = '"+manualTag.getLocation()+"'" ).getResultList();

}



      any help will be appreciated.
      Thanks in advance
