RichFaces and Facelets integration

bitec Dec 21, 2008 5:48 PM

I tried to integrate Facelets to the existing RichFaces + JSF RI + Tomahawk project, but faced some problems. What I did:

1. Added facelets view handler to faces-config.xml

<application>
 <view-handler>com.sun.facelets.FaceletViewHandler</view-handler>...
</application>

2. Changed .jsp to .xhtml for files
3. Changed <@%taglib...> directives to <html xmlns...>:

I tried to load simple login.xhtml, the page loaded and all <h:input> tags were rendered correctly, but <rich:..> tags were not rendered correctly(e.g. <rich:spacer height="300"/> resulted in also "<rich:spacer height="300"/>" on html page and it was ignored by browser). It seems, that AjaxViewHandler was not used during parsing tags. I know, that a lot of people use Facelets with Jsf and Richfaces, so it shouldn't be difficult to find the reason.

Thanks in advance!

our richfaces demo built on top of the JSF and facelets. please check carefully RF components namespaces.

I found the reason, richfaces.taglib.xml and ajax4j.taglib.xml were not loaded correctly by facelets, here is the stack:

I looked through all libraries, there is no more class with "ActionParamHandler" name except in richfaces-ui-3.2.2.SR1.jar and it extends facelets TagHandler class, but the error stack says the other thing... It's pretty strange..

The topic is closed, I had facelets library both in web application libraries and in tomcat libraries, this affected the class loading somehow... Childish thing, thx to everyone :)
