问题 I was working on a JSF 1.x example, which has some EL conflict in JSPs. the line actionListener="#{helloBean.addControls} is shooting an issue.

JSP.2.3.4 does not permit literal values in this case My project Description is as follows : Package Structure : Maven Dependencies : <project xmlns="http:/

问题 I have an ADF web application with Faces 1.2 In my managed bean I am trying to access the parameters of the post request, but always getting null. This is my post form that I am posting to the Faces: <form name="input" action="http://127.0.01:7072/myapplication/faces/login.jspx" method="post"> <input type="hidden" name="user" id="user" value="myUserName"/> <input type="submit" value="Submit"/> </form> FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("user");

问题 I need to implement long polling or pending request for a chatroom. I tried a4j:push, but it seems doesn't work like a real long polling approach (see the following discussion: https://community.jboss.org/message/16614). The question is: which alternatives do I have to realize long polling? I'm using JSF 1.2, JAVA EE 6 and RichFaces 3.3.2. Thaks in advance! 回答1: You need to use the a4j:poll component from RichFaces.

问题 When using the <a4j:support> like described in the RichFaces example I'm always getting the following error when changing the value of the drop-down-box. Expected a child component type of UISelectItem/UISelectItems for component type javax.faces.SelectOne(myId). Found null. Here's the JSF code: <h:selectOneMenu id="selectId" valueChangeListener="#{cs.myListener}" value="#{cs.selectList.selectedItem}"> <f:selectItems value="#{cs.bundeslandList.selectItems}" /> <a4j:support event="onchange"

问题 There are some answers on stackoverflow, but no one fits my needs :( I'm trying to conditionally build a <ui:param /> for my parent template with JSTL. Something like this: <ui:composition ... template="template.xhtml"> <c:if test="#{condition}"> <ui:param name="parameter" value="parameterValue" /> </c:if> <ui:define name="insertName"> {...} </ui:define> </ui:composition> I tried with both namespaces for JSTL: http://java.sun.com/jstl/core and http://java.sun.com/jsp/jstl/core, but neither
