[TYPO3-Solr] Problem with Facet Renderer after upgrade

[Kerstin Huppenbauer]

Hi,

after upgrade of the Solr Extension from 1.7.0 to 2.7.1
my Facet Renderers doesn't work anymore.
How can I achieve the Rendering of the Facets through a PHP Class or 
Template now?

This is my Configuration which worked in 1.7.0 fine:

facets{
   category{
     label=category
     field=category_stringS
     sortBy=index
     keepAllOptionsOnSelection=1
     renderer=tx_dgpmediasearch_solr_facet_dropdown
   }
   fileType{
     label=fileType
     field=fileType_stringS
     keepAllOptionsOnSelection=1
     operator=OR
     renderer=tx_dgpmediasearch_solr_facet_checkbox
   }
}

Cheers
Kerstin
