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
anonymous wrote :
|
| xhtml @69,119 binding="#{categoryMangager.updateAssortmentCategories}":
Target Unreachable, identifier 'categoryMangager' resolved to null
|
|
I get the error
anonymous wrote :
|
| <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
anonymous wrote :
|
| @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;
| }
| }
|
| ...
|
| }
