    Injecting stateful into stateful bean problem

    Bogdan Minciu Newbie

      Hello,


      I have this class:


      @Stateful
      @Name("categoryList")
      @Scope(ScopeType.SESSION)
      @Restrict("#{identity.loggedIn}")
      public class CategoryListBean implements LocalCategoryList {
      
          @Logger
          private Log log;
      
          @In
          private XTextSessionWrapper xtw;
      
          public String getName(Category category) {
              return getXtw().getText(category.getId() + ".name");
          }
      ...
      }
      


      which as you can see injects another stateful component, also scoped to session:


      @Stateful
      @Name("xtw")
      @Scope(ScopeType.SESSION)
      @AutoCreate
      public class XTextSessionWrapper implements LocalXTextSessionWrapper {
      
      ...
      public String getText(String identifier) {
          return "It works!";
      }
      ....
      



      So, when trying to access xtw.getText() method from a JSF like this:


      <h:dataTable id="categories" value="#{categories}" var="category" rendered="#{categoryList.resultListSize>0}">
      ...
                          <h:column>
                              <f:facet name="header">Name</f:facet>
                              #{categoryList.getName(category)}
                          </h:column>
      ...
      </h:dataTable>
      



      I get this error:
      (I don't get why my object had suddenly became org.javassist.tmp.java.lang.Object_$$_javassist_4 and not com.brit.xcms.interText.XTextSessionWrapper as speciffied)

      I tried debugging, and it really seems that my xtw component has class=class org.javassist.tmp.java.lang.Object_$$_javassist_4


      Thanks in advange for any hint in solving this issue,
