Subject Ajax4Jsf component not rendered
Date Mon, 29 Jan 2007 14:45:40 GMT
Hi All,

So far, I have been using Trinidad and Seam together without too much fuss.
Now I've tried to add Ajax4Jsf into the mix, I'm having some trouble getting
Ajax4Jsf to work.  My pages are being rendered without throwing an exception
however the Ajax4Jsf components are just being ignored.  I've added a simple
poller to my page as follows:

<!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:tr="http://myfaces.apache.org/trinidad"
      xmlns:a4j="https://ajax4jsf.dev.java.net/ajax">

<ui:composition template="../public/common.xhtml">
  <ui:define name="body">

<form jsfc="tr:form">
  <a4j:poll interval="1000" action="#{paymentBean.pollPaymentStatus }" />
</form>

  ...
  </ui:define>
</ui:composition>
</html>

At render time, the poller is ignored and nothing is added to my page, hence
no polling.  I get output like this repeated about 12 times despite there
only being one instance of the poller:

14:04:26,453 ERROR [STDERR] 29-Jan-2007 14:04:26
org.apache.myfaces.trinidadinternal.renderkit.RenderKitBase getRenderer

14:04:26,453 WARN  [UIComponentBase] No Renderer found for component

/view/secure/payment-processing.xhtml]} (component-family=
javax.faces.ViewRoot, renderer-type=javax.faces.ViewRoot)

I have used the poller successfully in a MyFaces/Facelets/Seam project that
doesn't use Trinidad.  Is there anything special that I need to do in order
to make these libraries play together?

My web.xml and faces-config.xml are below.

Any help will be greatly appreciated.

Best Regards,

Chris.
