We are upgrading from jsf 1.2 to jsf 2. We are using apache myfaces 2.1 and rich faces 4.3.
The issue is , it seems that <a4j:commandButton> tag AJAX feature is broken.
Below is the xhtml file.
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:a4j="http://richfaces.org/a4j"
xmlns:rich="http://richfaces.org/rich">
<h:form prependId="false" id="questionsForm">
<!-- other form fields are not shown -->
<a4j:commandButton id="questions" value="Clear" action="#{bean.clearAction}"/>
</h:form>
</html>
When the "clear" button is clicked , back end code executes but an entire page reload happens (page refreshes again). Pre-migration code works perfectly fine with no page reload.
Can anyone please help in how to get this AJAX work in rich faces tags ?
As given attributes you have to tell
a4j:commandButton,The first is done with the attribute
execute, the last is done with the attributerender. If none of both is given, the button behaves like a traditionalh:commandButton(which explains the described behaviour)Update: Also check that the
<head>and<body>tag have to be like<h:head>and<h:body>so JSF has a chance to add mandatory javascript- and css libraries.Update: Have you double-checked your action returns void/""/
nulland not any forwards? (see also "a4j:commandButton makes a full page reload RichFaces 3.3.3 CR1")
