[TYPO3-calendar] cal typo3 6.2 and lightbox not working

[Ingo Lacheiner]

Hallo!

In Eventview I want to use a lightbox. In tt_content all works fine with the lightbox (no extension). But in Cal Eventview the a tag around the picture has no class="lightbox" nor the rel-Attribut.

I am using the normal ts_standard Typoscript. 

# @description	Content object for event image
				image =< tt_content.image.20
				image {
					preRenderRegisters.allImageCaptions.cObject {
			            references {
				        	table = tx_cal_event
				            uid.data = uid
				            fieldName = image
				        }
				        renderObj.data = title
				    }
				    
				    imgList.cObject.references < plugin.tx_cal_controller.view.event.event.image.preRenderRegisters.allImageCaptions.cObject.references
						
					//17 = in text right
					textPos.override = 17
					layout.key.override = 17
					1 {
						imageLinkWrap {
							# We just need a value > 0, which could be pid or uid ;)
							enable.field = uid
							typolink.ATagParams.dataWrap = class="{$styles.content.imgtext.linkWrap.lightboxCssClass}" rel="{$styles.content.imgtext.linkWrap.lightboxRelAttribute}"
						}
					}
					
					imgMax = 4

					stdWrap.required = 1
					stdWrap.dataWrap = <div>%%%IMAGE_LABEL%%%:  |</div>
					
					maxW = {$plugin.tx_cal_controller.singleMaxW}
					
				}

But typolink.ATagParams.dataWrap does nothing. The constants are set correctly. 
If i write rel and class-Attribute via Firebug into the a-Tag everything works fine.

Thank you for your hints or help.
