Problem when using for criteria in query an object with composite key --------------------------------------------------------------------- Key: HHH-683 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-683 Project: Hibernate3 Type: Bug

Environment: Hibernate 3.0.5, Oracle 9.2.0.1 Reporter: George Gaviotis Priority: Critical

(see also http://forums.hibernate.org/viewtopic.php?t=944280&sid=aad3d7e0696d39... in forums) I am having problem to query on a persistent class using as a parameter an object that has a composite key. It seems that the problem is the way the oracle sql is created. Unfortunately we cannot avoid having composite keys. Four classes are involved in the example below, 3 of them are persistent and the fourth is an Id class for the composite key.
