Hello, I'm not sure what are you trying to achieve with 'anonymous' reference, but that error happened because both ref1 and ref2 has the same "implicit collection property on the referenced class" called "foofoo_set" (<name-of-class>_set)
Maybe you can set each of them to have different name using collection_name parameter when you declare the model's property.
