title: Hybris ProductListPage does not find category
body: <p>here is my question. I have one ProductListPage where I want to display a single product. I have a simple Product catalog with one category "TestCategory" and one product assigned to it "TestProduct". What I want is just to display the product in my Product List Page.</p>
  
  <p>However, when I access the Product List Page, there is a message stating:</p>
  
  <p>Category with code 'TestCategory' not found! (Active session catalogversions: ProductTestCatalog.staged, ContentTestCatalog.staged)</p>
  
  <p>Both content and product catalogs are synched and everythings seems fine. I started an indexer operation wizard and it was successful, but nothing has changed, I keep getting this message, even though the category is existing - it even comes with the name "TestCategory not found" What should I do to find it?Can you provide any ideas or solution to this problem? Maybe the problem is in my Solr Configuraiton? If yes, any ideas how to fix it will be highly appreciated. Thanks! :)) </p>
