Hi

I am using the Product catalog for ViewModel to render a product list. I am using the standard product list template "ProductViewListFacets.cshtml" to render the list. That works well, the product list with facets is rendered. But when using a filter on the page I get this .Net error. What can be the problem?

An error occurred while attaching module (Dynamicweb.Frontend.Content)
System.NullReferenceException: Object reference not set to an instance of an object.
   at Dynamicweb.Ecommerce.ProductCatalog.ViewEngine.CreateProductGroup(ProductGroupViewModelSettings settings, ViewModelPropertyFiller`1 filler, Group group)
   at Dynamicweb.Ecommerce.ProductCatalog.ViewModelPropertyFiller`1.Fill[S](T model, String propertyName, Func`1 source)
   at Dynamicweb.Ecommerce.ProductCatalog.ViewEngine.CreateView(ProductListViewModelSettings settings, Group group, IList`1 products)
   at Dynamicweb.Ecommerce.ProductCatalog.ProductCatalogFrontend.RenderProductList(ProductCatalogSettings settings, String groupId)
   at Dynamicweb.Ecommerce.ProductCatalog.ProductCatalogFrontend.GetContent()
   at Dynamicweb.Frontend.Content.GetModuleOutput(Paragraph paragraph, PageView pageview)

Seems like a product that does not belong to a group...?

You should not get the exception though, so if that is the case, we also have a bug to fix.

Hi Nicolai

Yes I've got a lot of products not related to a group. So that's not allowed anymore?

I do get the exception.

Well, the code does not take it into consideration. But it is allowed, so consider it a bug!

Already made a bugfix for it - will be out in ecommerce package very soon.
