How to use namedQueries in Grails 1.3.7 with object containing object?

I have these classes:

class Category {
  Set usersLinked
  def hasMany = [usersLinked:CategoryUserLink]  
  static namedQueries = {
    getAuthorizedBusiness { auser ->
        eq "business", true
        usersLinked{
            eq "user", auser
            type{
                eq "name", "Authorized"
            }
        }            
    }
  }
}
class CategoryUserLink {
  开发者_StackOverflow社区User user
  CategoryType type
  Category category
}

When I querying on it with a namedQuery or a createCriteria I receive an error:

Category.getAuthorizedBusiness(user).list()

No such property usersLinked

Why?

I receive this error message:

 org.hibernate.QueryException: could not resolve property: userslinked of: lli.faqapp.domain.Category
    at grails.orm.HibernateCriteriaBuilder.invokeMethod(HibernateCriteriaBuilder.java:1223)

And after removing the plugin GormLabs, I start the integration test and I receive this message:

 org.hibernate.QueryException: could not resolve property: userslinked of: lli.faqapp.domain.Category
    at grails.orm.HibernateCriteriaBuilder.invokeMethod(HibernateCriteriaBuilder.java:1223)

hasMany must be static - it's a property of the Class, not a specific instance. The Set usersLinked that it generates is instance-specific, but the hasMany declaration is for the Class.
