Hello All,

I am doing migration from Richfaces 3.x to 4.x with jsf 2 integration

I have followed the richfaces live demo exadal but when i am trying to apply rich panel

I did not get the panel box, i only get the data which has placed inside.

<ui:define name = "maincontent">

        <rich:panel header="Panel with default Look-n-feel">

        <f:facet name="header">Sample panel </f:facet>

          RichFaces is a component library for JSF and an advanced framework for.

        <ul>

            <li>100+ AJAX enabled components in two libraries</li>

        </ul>

    </rich:panel>

</ui:define>
