    bijection scope problem

    Simon Bailey Newbie

      hi,


      i'm having a problem with bijection in conversation scope. i have two beans, one which is accessed from the first page and shows a list of categories, this bean oujects an Enum value to conversation scope:


      @Name("competitionCategories")
      public class CompetitionCategories {
      
           private List<Category> categoryList;
           @RequestParameter
           private Long competitionId;
           
           @In 
           EntityManager entityManager;
           
           @Out(required=true,scope=ScopeType.CONVERSATION)
           DemandMode mode = DemandMode.STANDARD;
      
              // getters and setters
      }
      



      the category display page:


      <h:dataTable id="competitionCategories" var="cat"
        value="#{competitionCategories.categoryList}" 
        rendered="#{not empty competitionCategories.categoryList}">
        <h:column>
          <f:facet name="header">Name</f:facet>
            #{cat.name}
        </h:column>
        <h:column>
          <h:form>
            <f:facet name="header">Actions</f:facet>
            <s:link id="categoryResults" value="View Results"
              view="/competition/competitionResults.xhtml" propagation="join">
              <f:param name="category" value="#{cat.categoryId}" />
              <f:param name ="competitionId" value="#{competitionCategories.competitionId}"/>
            </s:link>
          </h:form>
        </h:column>
      </h:dataTable>
      



      categoryList.xhtml has #{conversation.begin} setup in pages.xml, links to competitionResults.xhtml propagate the conversation. i have the following bean referenced from competitionResults.xhtml:


      @Name("competitionResults")
      public class CompetitionResults {
           
           @In(required=true)
           DemandMode mode; // TODO: making required=true and resolving the dependencies of all pointing pages
           @In(required=false)
           QueryParameterList params;
           @In(required=false)
           String whereClause;
           @RequestParameter
           Long competitionId;
           @RequestParameter
           Long category;
           @Logger
           Log log;
           @In
           Session termcompSession;
           @SuppressWarnings("unchecked")
           @In
           CacheProvider cacheProvider;
      
              // getters, setter, businessmethods
      }
      



      if i inspect the conversation in debug.seam, i can see that mode has been outjected into the conversation scope, but it is not being injected into CompetitionResults.java. if i change the declaration in CategoryList.java to @Out(scope=ScopeType.SESSION) it does get injected.


      what am i doing wrong? am i doing anything wrong?


      regards,
      sb

          Hi



          Can you be sure that bothe outjection and injection occur to the same conversation?
          Chances are you're outjecting to one conversation and expecting a injection in another conversation.


          Just a hunch, but do you actually start or join a long-lived conversation? (@Begin)



          hope I could be of some sort of help,
