-----------------------------------

Hello Ali,

I am trying to apply your suggestion but I can not see how this exception thrown form CriteriaQueryTranslator#createAssociationPathCriteriaMap is avoided.

Do you mean I should somehow extends CriteriaQueryTranslator and not to call createAssociationPathCriteriaMap from the constructor also? (Because I don't see JoinWalker.isDuplicateAssociation method is called in the trace bellow)

I am taking about org.hibernate.QueryException: duplicate association path: impactImperatives
at org.hibernate.loader.criteria.CriteriaQueryTranslator.createAssociationPathCriteriaMap(CriteriaQueryTranslator.java:141)
at org.hibernate.loader.criteria.CriteriaQueryTranslator.<init>(CriteriaQueryTranslator.java:80)
at org.hibernate.loader.criteria.CriteriaLoader.<init>(CriteriaLoader.java:58) 
(using Hibernate3.1.3)

Or are you guys taking about a different thing?

BTW, I could make an external Util method that can retrieve the Subcriteria for the same path for the duplicated path and it was working fine. But this time I faced the situation that requires the duplicated path Subcriteria with a different 'alias'.

Best Regards,
    Tsuyoshi
