Hi,

i use RichFaces 4.0.0 with IE 8.  I implemented a RichFaces tooltip as following:

<a4j:commandLink id="addRowLink" styleClass="no-decor" action="#{cc.attrs.action}"
        render="#{cc.attrs.render}">
        <rich:tooltip id="addRowLinkToolTip" for="addRowLink" mode="ajax"
            styleClass="tooltip" showDelay="800" followMouse="false"
            layout="block">
            <h:outputText styleClass="feldcomment"
                value="#{cmp.Zeile_hinzufügen}" />
        </rich:tooltip>
        <h:graphicImage value="/images/icons/add-button.jpg" alt="add" />
    </a4j:commandLink>

When I click on the link I got following error:

'tooltip.popup' is null or not an object  tooltip.js.jsf?ln=org.richfaces, line 245 character 21

What could be the problem?

Thx

Mathias
