Thank you Howard for your feedback - it is great from you!

I have a DataView with only one summary column - but it doesn`t work.
Do I have to import any .css or motives?

the code:
 <xe:dataView id="dataView1" rows="10"
    pageName="/mobileCustomer.xsp" openDocAsReadonly="true">
    <xp:this.facets>
     <xp:link escape="true" text="mehr" id="link1"
      xp:key="pagerBottom">
      <xp:eventHandler event="onclick"
       submit="false">
       <xp:this.script>
        <xe:addRows for="dataView1"
         disableId="link1">
        </xe:addRows>
       </xp:this.script>
      </xp:eventHandler>
     </xp:link>
    </xp:this.facets>
    <xe:this.data>
     <xp:dominoView var="view1"
      viewName="mobileCustomer">
     </xp:dominoView>
    </xe:this.data>

    <xe:this.summaryColumn>
     <xe:viewSummaryColumn columnName="txtCompany">
     </xe:viewSummaryColumn>
    </xe:this.summaryColumn>
   </xe:dataView>

Thank you!
