[TYPO3] Rendering special way content elements

[Tapio Markula]

Hi

I got this kind of code
styles.content.getBorder >
styles.content.getBorder = COA
styles.content.getBorder {

         # Render all content elements, except the last one - was 
previous bottomBRLast for the last item
         10 = CONTENT
         10 {
                 table = tt_content
                 select.orderBy = sorting
                 select.where = colPos=3
                 select.languageField = sys_language_uid
                 select.max = total-1
                 renderObj < tt_content
                 renderObj.stdWrap.wrap = |<img 
src="/fileadmin/template/main/kuvat/viiva268.gif" width="268px" 
height="4px" />
         }

         # Render the last content element.
         20 < .10
         20.select.max >
         20.select.begin = total-1
         20.renderObj.stdWrap.wrap = |<img 
src="/fileadmin/template/main/kuvat/viiva268.gif" width="268px" 
height="4px" />

}


That works *olmost* but if there is just one content element, it renders 
it *twice*

maybe need to count somewhat elements and if just one, don't render 
section '20' - how to do that
