Hallo I have a Problem with the Modal Panel. I wan't to include a modal Panal in a JSF Page put when i click the Link to open the Panel a JavaScript Exception is thrown. $(id) has no properties.

I don' know where the Problem is because it is the same Code as in the Domo of the RichFaces Demopage.

...
 <htm:td>
 <f:verbatim>
 <a href="javascript:Richfaces.showModalPanel('mp',{width:450, top:200})">irgendwas</a>
 </f:verbatim>
 <rich:modalPanel id="mp" minHeight="200" minWidth="450" height="200" width="500" zindex="2000">
 <f:facet name="header">
 <h:outputText value="Modal Panel Title" />
 </f:facet>
 <f:facet name="controls">

 </f:facet>
 <p>Any JSF content might be inside the panel. In case of using
 Facelets or JSF 1.2, it might be any mixed content.</p>

 <p>The RichFaces modal panel is good with <a4j:include> to create
 a wizard like behavior.</p>
 <p>The model panel is open and closed from the javascript function
 on <i>Richfaces</i> object. The following code
 <a href="javascript:Richfaces.hideModalPanel('mp')">hide this panel</a>:
 Richfaces.hideModalPanel('mp')</p>
 </rich:modalPanel>
 </htm:td>
