Code

class Member{
         string name          
        }



  class Group{
      string name
      static hasMany = [member: Member]
}

//CONTROLLER

def member = Member.get(1)               // I get member object as expected
def group = Group.findByMember(member)   //ERROR

Question

it is not possible to find a group like this…. (since group and member is in one to many relationship)

is there any other simple way?
