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

Question

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 didn't try, I need transaction in these code. Now my walk around is add A.withTransaction around the list{...} code. But I want to know the reason. – Xilang Nov 23 '11 at 01:33

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.
