    entityhome as attribute of my class

    Alexei R Newbie

      I'm trying to use the entityhome as attribute of my manager class




      @Name("editManager")
      @Scope(ScopeType.CONVERSATION)
      public class EditManager {
           
           @Logger     Log log;
           @In StatusMessages statusMessages;
           
           
           private BookHome bookHome;
      
      
              public BookEditManager() {
                this.bookHome = new BookHome();
      
      
                
           




      in my editPage.xhtml I have this:




      <h:form>
          <rich:panel>
              <f:facet name="header">Book Details</f:facet>
      
       
              <s:decorate id="id" template="/layout/display.xhtml" >
                   <ui:define name="label">Id</ui:define>
                  <h:outputText value="#{bookEditManager.bookHome.instance.id}"/>
              </s:decorate>
              <s:decorate id="title" template="/layout/display.xhtml" >
                   <ui:define name="label">Id</ui:define>
                  <h:inputText value="#{bookEditManager.bookHome.instance.title}"/>
              </s:decorate>
      
                      
      
              <div style="clear:both"/>
      
          </rich:panel>       
                <h:commandButton action="#{bookEditManager.bookHome.update}" value="Salvar" />
           </h:form>




      When I clic the save button the book entity is saved but I got an error
