Hi

Hope someone can help on this. I am running richfaces 4.0 using tomcat 6.0.32 on a linux server. I have the following index.xhtml fiie which consists of a simple tab panel and some collapsible panels in the tabs. There are no backing(managed) beans just this file for now in my project.

<h:form id="form">
        <rich:tabPanel switchType="client" >
            <rich:tab header="Overview">
                <rich:collapsiblePanel header="Overview" switchType="client" styleClass="overview-collapsible-panel">
                    <div class="overview-label-wrapper">
                        <span class="overview-label">Total Number of Applications:</span> 5
                    </div>
                </rich:collapsiblePanel>
                <rich:collapsiblePanel header="Licensing" switchType="client" styleClass="overview-collapsible-panel">
                    <div  class="overview-label-wrapper">
                        <span class="overview-label">Total Number of Licenses Available:</span> 10
                    </div>
                </rich:collapsiblePanel>
            </rich:tab>
            <rich:tab header="Options"> 
                <rich:collapsiblePanel header="General Options" switchType="client" 
                           styleClass="overview-collapsible-panel">
                        <div class="options-input">
                            <rich:select value="0">
                                <f:selectItem itemValue="0" itemLabel="Trace"/>
                                <f:selectItem itemValue="1" itemLabel="Info" />
                            </rich:select>
                        </div>
                </rich:collapsiblePanel>
            </rich:tab>
        </rich:tabPanel>
    </h:form>

when I try to access it I get the following weird error:
