I have created a view in order to create a block for slide show in drupal 7. in my view I used a conditional field. this field get the id of node from url so I set "When the filter value is NOT available" to "Provide default value " and in TYPE drop down menu I set "Content ID From URL"

this view works with no problem. but when the view is empty (there is no raw for fetched parameter value from url) I see some rendered codes.

    <div id="block-views-coupon-slides-block" class="block block-views clearfix">
 
    
  <div class="content">
    <div class="view view-coupon-slides view-id-coupon_slides view-display-id-block view-dom-id-90e27feb6919634c2f506f189c503c01">
        
  
  
      <div class="view-content">
      
 <div class="skin-default">
      <div class="views-slideshow-controls-top clearfix">
      <div id="widget_pager_top_coupon_slides-block" class="views-slideshow-pager-fields widget_pager widget_pager_top views_slideshow_pager_field views-slideshow-pager-field-processed">
  </div>
    </div>
  
   <div id="views_slideshow_cycle_main_coupon_slides-block" class="views_slideshow_cycle_main views_slideshow_main viewsSlideshowCycle-processed"><div id="views_slideshow_cycle_teaser_section_coupon_slides-block" class="views-slideshow-cycle-main-frame views_slideshow_cycle_teaser_section">
  <div id="views_slideshow_cycle_div_coupon_slides-block_0" class="views-slideshow-cycle-main-frame-row views_slideshow_cycle_slide views_slideshow_slide views-row-1 views-row-odd">
  <div class="views-slideshow-cycle-main-frame-row-item views-row views-row-0 views-row-first views-row-odd">
  </div>
</div>
</div>
</div>
  </div>
    </div>

what is your solution for this problem? As I know when a view returns no row, it must not be rendered in source code. In above codes, you see there is no result but the codes of block are printed !!!

Thanks a lot for your guidance.
