[TYPO3-dev] tx_news categories setting by get param

[am at break-media.com]

Hello all, 

I'm trying to show on the detail page of tx_news a list of news items  
which are in the same category as the current news item. 

Is there any solution? 

I already tried to add a GET param and use it in Typoscript with  
something like:

lib.relatedNews = USER
lib.relatedNews {
  userFunc = TYPO3\CMS\Extbase\Core\Bootstrap->run
  extensionName = News
  pluginName = Pi1
  vendorName = GeorgRinger

  switchableControllerActions {
        News {
          1 = list
        }
  }

  settings < plugin.tx_news.settings
  settings {
categories = TEXT
categories.data = GP : test
  }
} 


But this does not work either, as tx_news does not recognize a value  
for categories with this approach. 

I also tried to set disableOverrideDemand=0 and add a  
tx_news_pi1[categories] param, also with no luck...


Thanks in advance, 

Adrian
