Is it possible 2 integrate the datascroller in a portlet ?!

Because i've implemented one, can see the right formatted table and the pagingbar, but when i click on a number or or an arrow 2 get 2 the next page the page isn't loading...

Do i have to implement a special attribute in my managed bean oder do i have to implement a special navigation rule !?

I'm using richfaces 3.0.1, ajax4jsf 1.1.1

My code looks like this ...

 <rich:tab label="Test">
 <rich:dataTable width="483" id="liste" rows="10" columnClasses="col" value="#{bean.testkonto}" var="category">
 <f:facet name="header">
 <rich:columnGroup>
 .
 .
 .
 </rich:columnGroup>
 </f:facet>
 <rich:subTable onRowMouseOver="this.style.backgroundColor='#D8D8D8'" onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'" var="expense" value="#{category.objects}">
 <rich:column>
 .
 .
 .
 </rich:column>
 </rich:subTable>
 </rich:dataTable>
 <rich:datascroller for="liste" maxPages="20"/>
</rich:tab>
