You should be able to use $this->_tables here as it was used here before.

listAll() returns the value of $_tables if it's already populated else fetches the list from the db. I think using the method is fine here. That way it doesn't need to rely on listAll() being called before this method is invoked.

That's correct. I initially used $this->_tables but found unit tests failed when findBelongsTo was called isolated. generateAssociations calls listAll as well as findHasMany and findBelongsToMany methods but findBelongsTo didn't.
