configurable Skinning with Richfaces

[baz]

Hello,
i do want to implement the configurable skinning shown in the richfaces demo.
So i have created a seam component called skinBean. And added in web.xml this parameter:

<context-param>
 <param-name>org.ajax4jsf.SKIN</param-name>
 <param-value>#{skinBean.skin}</param-value>
 </context-param>

but with no success. I thought that this is because ajax can not access seam components so i took the original skinBean from the example, renamed it to managedSkinBean and configured it as a managed bean in faces config. And of course changed the parameter shown above to managedSeamBean
But i get this exception again:

Any ideas why this happens?

You might take a look at the wiki example app. They use a fairly clever way of skinning which I've now adopted. You basically expose a bean with constants and reference that from the pages. It's then simple to specify new sets of files for your theme, which in the wiki example also includes the template.

Which wiki example do you mean?
The seam one does not use richfaces and i have to skin richfaces components. Hence i have to set the parameter.

i tke it back. Where to fast.
Will investigate thre wiki example.
But i am interestetd why the mentioned error occurs
