GORM,get org.hibernate.HibernateException: Found two representations of same collection when open transaction in afterLoad()

class A {
  def afterLoad() {
    A.withTransaction {

    }
  }
}

Most case, it works, until I call below list in controller

A.createCriteria().list{.....}

will throw exception:org.hibernate.HibernateException: Found two representations of same collection

If I remove 

A.withTransaction

It will then works.

I've come across this exception myself and I was really stumped on it for a few days. You can see if the solution to this question solves your problem:

HibernateException: Found two representations of same collection

That solution didn't work for me, so I wrote an article describing the issue and what I did to solve it that you can read here. I believe your problem is similar to mine because of the transactional aspect, Hibernate is flushing the session when the transaction is committed and that's where the exception is thrown.

may be 

A.withNewSession { session ->
  ....
}

will help you
