Hi, today I had a problem in Seam using the togglePanel component, in simple words I have a toggle panel with 2 states, the first has just 1 link, if I click it will switch to an edit input control and a button to save the control. When I click the first button I set the bean to edit (that is null at first) but when I try to save it I get a NPE like as the conversation was closed. This is my code: view: | <rich:togglePanel id="gctp" switchType="client" stateOrder="txt,edit" > | <f:facet name="txt"> | <h:panelGroup> | <rich:toggleControl for="gctp"> | <a:commandLink value="Aggiungi gruppo" action="#{homepageHelper.preparaAggiuntaGruppo}"></a:commandLink> | </rich:toggleControl> | </h:panelGroup> | </f:facet> | <f:facet name="edit"> | <h:panelGroup> | <h:outputText value="Gruppo: "></h:outputText> | <h:inputText value="#{homepageHelper.gruppoEdit.descrizione}"></h:inputText> | <rich:toggleControl for="gctp"> | <a:commandLink action="#{homepageHelper.salvaGruppo}" value="Salva" /> | </rich:toggleControl> | </h:panelGroup> | </f:facet> | </rich:togglePanel> | bean (Scope=CONVERSATION): | @Name("homepageHelper") | @Scope(ScopeType.CONVERSATION) | public class HomepageHelper implements Serializable { | | private Gruppo gruppoEdit; // gruppo usato per l'aggiunta o la modifica | | public Gruppo getGruppoEdit() { | if (gruppoEdit==null) { | gruppoEdit=new Gruppo(); | System.out.println("NEWGET"); | System.out.println("HPH: "+this); | } | System.out.println("GET"); | return gruppoEdit; | } | | public void setGruppoEdit(Gruppo gruppoEdit) { | System.out.println("SET: "+gruppoEdit); | System.out.println("HPH: "+this); | this.gruppoEdit = gruppoEdit; | } | | public void preparaAggiuntaGruppo() { | Gruppo g = new Gruppo(); | g.setContatto(loggedUserManager.getLoggedUser()); | g.setDescrizione("nuovo"); | System.out.println("pag"); | setGruppoEdit(g); | } | | public void preparaModificaGruppo() { | setGruppoEdit(getGruppoSelezionato()); | } | | public void salvaGruppo() { | // Se sono in modifica | System.out.println("GE: "+getGruppoEdit().getDescrizione()); | System.out.println("HPH: "+this); | /*if (entityManager.contains(getGruppoEdit())) { | entityManager.merge(getGruppoEdit()); | } else { | entityManager.persist(getGruppoEdit()); | } | entityManager.flush(); // Salvo | */ | } | | ... | where do I wrong? I noticed during my tests that the conversation object HomepageHelper has different instances between switching. Also I tried to do now use togglePanel and it works, like that: | <a:form id="gcform"> | <a:commandLink value="Aggiungi gruppo" action="#{homepageHelper.preparaAggiuntaGruppo}" reRender="gcform"></a:commandLink> | <h:outputText value="Gruppo: "></h:outputText> | <h:inputText value="#{homepageHelper.gruppoEdit.descrizione}"></h:inputText> | <a:commandLink action="#{homepageHelper.salvaGruppo}" value="Salva" reRender="gcform"/> | </a:form> | I don't know if it is a seam problem or a richfaces problem (or my problem :D) so I post this in both the forums... thanks Demetrio Filocamo View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4078121#...
