Filter

I created an exposed filter with views and thos moudle following the instructions here #2059949: Example usage?
Filtering works but if i allow multiple selections the filter doesnt wprk anymore. Is that by design or has anyone this working?
Maybe its just a bad idea to reference stuff if you need to filter by references?
In my case i have a recipe for like a cake and this cake node references all ingredients. Later i want to be able to make a view and like filter all cakes that use butter as an ingredient.

Thank you for your opinions.
