[Tomahawk] Popup don't work

[Christian Wiesing]

Hello,

i have a problem with <t:popup>. I never get a popup window. I tried it 
as follow:

               <t:popup id="infoPopup"
                        styleClass="popup"
                        closePopupOnExitingElement="false"
                        closePopupOnExitingPopup="false"
                        displayAtDistanceX="10"
                         displayAtDistanceY="10">
                    <h:outputText id="info" value="info"/>
                   <f:facet name="popup">
                       <h:panelGroup>
                             <h:panelGrid columns="1">
                               <h:outputText id="testOutput" 
value="Test output"/>
                           </h:panelGrid>
                       </h:panelGroup>
                   </f:facet>
               </t:popup>

Is there any configuration (or something like that) that i have to use 
to get it working?

I use MyFaces 1.4, Tomahawk 1.3 and Facelets.

regards,

Christian
