问题 I get the below error, when setting the scope for the managedBean as ViewScoped. Below is the exception Im getting when trying to invoke the page javax.faces.FacesException: java.io.NotSerializableException: javax.faces.model.ListDataModel at com.sun.faces.renderkit.ResponseStateManagerImpl.getViewState(ResponseStateManagerImpl.java:137) at javax.faces.application.StateManager.getViewState(StateManager.java:555) at com.sun.faces.context.PartialViewContextImpl.renderState

问题 Every time I try to inject a session-scoped bean into my view-scoped beans, I get a NullPointerException when calling said bean. This problem is directly related to auto -instantiate a session bean? Here is what I tried so far: faces-config.xml <managed-bean> <managed-bean-name>sessionBean</managed-bean-name> <managed-bean-class>com.example.SessionBean</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean> <managed-bean> <managed-bean-name>viewBean</managed-bean

问题 Been at this problem for a while and I am kind of stuck. Using: JSF 2.0, Primefaces 3.5, Weblogic Server 10.35, IE 9 Problem: Sometimes ajax request are not processed correctly and you need to click multiple times to get the desired outcome. When I debug JSF phases I can see that after phase 1, restore view, the render response phase is executed skipping update model and the invoke application phase. I have striped my application to the bare minimum and the problem still occurs. xhtml: <h

问题 I have been using the following bit of code in a servlet to locate a session backing bean (as suggested by BalusC) without problems until recently. Now it only works on Internet Explorer. Chrome and Firefox appear to be getting a totally new backing bean rather than the original backing bean. When calling functions in the backing bean, it falls over with null pointer errors for objects in the backing bean that were definitely initialized in the original. FacesContext facesContext = FacesUtil

问题 I am displaying a list of items with links in my xhtml page. When I click my "back to previous page" button from that link, I basically reset the flags in my bean to indicate to the xhtml which page to display, and reload the list of links from my database. When I click the same link (or any other link for that matter) in this new page, I get this error: javax.portlet.faces.BridgeException: javax.portlet.faces.BridgeException: javax.faces.FacesException: Unexpected error restoring state for

问题 I have this Dialog: <p:dialog header="Ingrese Comentario" widgetVar="dlg1" appendTo="@(body)" modal="true" position="top" hideEffect="fold" showEffect="fold" closable="true" draggable="true" > <h:form id="d_ingresarComentario"> <h:panelGrid columns="2"> <p:inputTextarea value="#{tareaController.comentarioNuevo.comentario}" rows="7" cols="60" placeholder="Ingrese su comentario aquí" counter="display1" maxlength="200" counterTemplate="{0} Caracteres faltantes." > </p:inputTextarea> <br/> <h

问题 I have a <p:selectOneMenu> component, that is fed with an Array of instances of some Class (say ClassABC). In the top of the selectItems list, I want to provide a <f:selectItem> that will serve as a Wildcard/Any option, and it's value should be a null object. I managed to make this work as <p:selectOneMenu value="#{someBean.selectedInstance}" converter="classABCDConverter" > <!-- Wildcard Value --> <f:selectItem itemLabel=" * Any * " itemValue="" /> <!-- Dynamic Data with Real Instances -->

问题 I'm trying to use PrimeFaces 3.2. I'm using Eclipse Indigo SR2. I'm creating a JSP page using PrimeFaces tags. The standard <h:commandButton> is working, but <p:commandButton> is not working. <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ taglib prefix="f" uri="http://java.sun.com/jsf/core"%> <%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4
