I have an entity type "Post" and I would like to create a view that will show one random Post with a given category. I created a Data pipeline that grabs all posts and I created a view with ListPresentation = a "TemplateSettings" entity type that lets me choose categories. 

I planned to use the Razor template to filter the items for those matching the categories in List.Presentation.Categories. But, I can't seem to reference List.Presentation.Categories. I get an error that System.Collections.Generic.List doesn't contain an entry for "Presentation". When I use @ListPresentation, the whole object in null... so @ListPresentation.Toolbar, etc. all throw errors, despite me having set a "Demo Item".

Can anybody see what would be wrong with this setup? How do I reference List Presentation stuff in Razor?

Thanks.
