    Bean access

    Urs Wagner Novice

      How have I to call the categoryManager bean. I should call method before the data model is loaded into the table. With the following construction



      xhtml @69,119 binding="#{categoryMangager.updateAssortmentCategories}": Target Unreachable, identifier 'categoryMangager' resolved to null



      I get the error



      <h:dataTable var="category" binding="#{categoryMangager.updateAssortmentCategories}" value="#{assortmentCategories}">
      <h:column>
      <h:outputLink value="">
      <h:outputText value="#{category.description}" />
      </h:outputLink>
      </h:column>
      </h:dataTable>



      The bean code part



      @Stateful
      @Scope(SESSION)
      @Name("categoryManager")
      @Interceptors(SeamInterceptor.class)
      public class CategoryManagerBean implements Serializable, CategoryManager {

      ...

      public void updateAssortmentCategories() {

      if (assortment != oldAssortment) {
      Query query = em.createQuery("from Category c where c.assortment = :assortment");
      query.setParameter("assortment", assortment);
      assortmentCategories = query.getResultList();
      oldAssortment = assortment;
      }
      }

      ...

      }
