    Problem reaching oujected object in the EVENT context

    Richard Leherpeur Novice

      Hello,

      I'm using jboss-4.0.5.GA and jboss-seam-1.1.1.GA.

      I define in pages.xml the following:

      <page view-id="/public/browseAction.xhtml" action="#{browseAction.perform}" />
      


      The action bean is defined by:

      @Stateless
      @Name("browseAction")
      @Scope(ScopeType.EVENT)
      public class BrowseAction implements Browse {
      
       @In(create=true)
       private EntityManager entityManager;
      
       @Out(scope=ScopeType.EVENT)
       private Category category;
      
       @Out(scope=ScopeType.EVENT)
       public List<CommonSearchRow> results = null;
      
       @Logger
       private Log log;
      
       public String perform() {
       System.out.println("######### void perform()");
      
       // Find the search data
       results = ...
      
       return "success";
       }
      
       public Category getCategory() {
       return category;
       }
      
       public void setCategory(Category category) {
       this.category = category;
       }
      
       public List<CommonSearchRow> getResults() {
       System.out.println("######### List<CommonSearchRow> getResults(): " + results);
       return results;
       }
      
       public void setResults(List<CommonSearchRow> results) {
       this.results = results;
       }
      }
      


      The success outcome is defined as a JSF navigation rule. In that result xhtml page, there are multiple call to getResults() as I need to check is that list has any elements and also I iterate over the list.

      <f:subview rendered="#{empty browseAction.results}">
       <div>
       <h:outputText value="#{messages.SEARCH_NO_RESULTS}" />
       </div>
      </f:subview>
      <f:subview rendered="#{not empty browseAction.results}">
       <table id="bodyTable" class="body">
       <c:forEach items="#{browseAction.results}" var="result">
       <tr id="#{result.id}">
       <td class="last"></td>
       </tr>
       </c:forEach>
       </table>
      </f:subview>
      


      Interestingly, the call to getResults() generated by #{empty browseAction.results} and #{not empty browseAction.results} always work, but then the next one due to #{browseAction.results} doesn't.
      (using ui:repeat doesn't change anything by the way).

      I get the follwoing stacktrace:
