Hi:

I am having a problem while showing an .xhtml (with templates) Facelets page. The trace error is shown below:

I cutted some lines because the structure is basically like the source shown above.

I am using glassfish 2 UR 2, Facelets 1.1.13, Richfaces 3.3.1 GA

Any ideas?

Thanks very much!

Thanks!

Oh, I see ok :). Can you add this to your web.xml?

Code: Select all

<context-param>
		<param-name>facelets.SKIP_COMMENTS</param-name>
		<param-value>true</param-value>
	</context-param>

Oh great it worked! Another question: How can I change the css of the p:layout and p:layoutUnit components? richfaces skin is blue but the p:layout uses grey as background ,for example).

Thanks very much again!

I haven't added a skinning guide to layout in reference documentation but it's based on YUI layout framework so easy to skin. Here's a full CSS guide;

thanks again!

It would be perfect if you could see why Primefaces fails in other of my post (export PDF with rich:datatable SerializableDataModel etc).

Thank you. I had the same problem and is also solved by:

<context-param>
<param-name>facelets.SKIP_COMMENTS</param-name>
<param-value>true</param-value>
</context-param>
