Ajax4jsf does no work

m.schuetz Nov 13, 2006 9:58 AM

Hi,

i'm using seam, facelets, ajax4jsf and myfaces - all in latest versions.

Following Code does NOT work in my Seam-Application - that means that the page appears but does nothing (asynchronously!) when triggering an event.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
 xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:a4j="https://ajax4jsf.dev.java.net/ajax"
 xmlns:h="http://java.sun.com/jsf/html"
 xmlns:f="http://java.sun.com/jsf/core">

<body>
<ui:composition template="/templates/defaultTemplate.xhtml">

 <ui:define name="siteTitle">
 Ajax Test
 </ui:define>

 <ui:define name="body">

 <f:view>
 <h:form>
 <a4j:region selfRendered="true">
 <h:panelGrid columns="2">

 <h:outputText value="Type the Text:" />
 <h:inputText value="#{useraccount.userName}">
 <a4j:support event="onkeyup" reRender="repeater" />
 </h:inputText>

 <h:outputText value="Text in the AJAX Response:" />
 <h:outputText id="repeater" value="#{useraccount.userName}" />

 </h:panelGrid>
 </a4j:region>
 </h:form>

 </f:view>

 </ui:define>

</ui:composition>

</body>

</html>

In a non-seam application all works fine.

Do you have an idea? Thanks

I'm having a similar issue. <a:outputPanel> only reRenders if I set ajaxRendered="true"

Just tried a seam example from CVS and it looks to work so I'm a little lost for a reason for my app not working.

Y'know, Todd and myself put a lot of work into building a nice example application that shows exactly how to use Ajax4JSF with Seam. Please follow the example, since otherwise you waste your time, my time, and everyone else here's time. Sheesh.

This is how you use Ajax4JSF with Facelets:

<context-param> <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name> <param-value>org.jboss.seam.ui.facelet.SeamFaceletViewHandler</param-value> </context-param>

(copy/pasted straight from the Seam 1.1 booking example)
