Transaction.instance().setRollbackOnly() or Transaction.instance().rollback()cause detatched entity

[alin.heyoulin.qq.com]

hi.
I have some confusion in CONVERSATION scope entitymanager.

I have a conversation scope compenent. When i call a function with
Transaction.instance().setRollbackOnly() or Transaction.instance().rollback() it will cause session closed and throw org.hibernate.LazyInitializationException: could not initialize proxy - no Session

have  anybody some suggestion?

Did you close or end your conversation explicitly? Check your code.

No.
If remove Transaction.instance().setRollbackOnly() it work fine.
Otherwise must change
 
  @Factory
     public void getFibres()
     {
          
     pageSize=pageSize==null?10:pageSize;
        String sql="from WsFibre i where lower(i.fibreNo) like :search " +
            "or lower(i.fibreType) like :search or lower(i.receiveNo) like :search " +
            "or lower(i.location) like :search or lower(i.selBatch) like :search " +
            "or lower(i.selBatch) like :search or lower(i.inBatch) like :search " +
            "or lower(i.outBatch) like :search " ;
                  
        fibres= entityManager.createQuery(sql)
                  .setParameter("search", getSearchPattern()).getResultList();
     }

to

  @Factory
     public void getFibres()
     {
          
     pageSize=pageSize==null?10:pageSize;
        String sql="from WsFibre i join fetch i.item where lower(i.fibreNo) like :search " +
            "or lower(i.fibreType) like :search or lower(i.receiveNo) like :search " +
            "or lower(i.location) like :search or lower(i.selBatch) like :search " +
            "or lower(i.selBatch) like :search or lower(i.inBatch) like :search " +
            "or lower(i.outBatch) like :search " ;
                  
        fibres= entityManager.createQuery(sql)
                  .setParameter("search", getSearchPattern()).getResultList();
     }



add  join fetch i.item
