[hibernate-issues] [Hibernate-JIRA] Resolved: (HSEARCH-306) Problem with composite key

[Emmanuel Bernard (JIRA)]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-306?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Emmanuel Bernard resolved HSEARCH-306.
--------------------------------------

    Resolution: Fixed

Please reopen if Core trunk and Search trunk are still showing the problem.
(intermittent issue is that Core has more Session.* methods than current Search and thus might fail but this will be resolved eventually (with core beta3 release we will align)

> When a composite key is used and more than one results are expected , the values passed to the query are not in a proper expected order.
> In the below query the parameters passed are (A00, A00),(A00, 1),(2,5) ....instead of the correct order which should be (A00,1) ,(A00,2), (A00,5)
> (I have omitted the select part)..
> ..
> where ((this_.key_client, this_.key_identifier) in ((?, ?), (?, ?), (?, ?)))
> I tried to debug this issue and found that in the class org.hibernate.criterion.InExpression, the method getTypedValues(Criteria criteria, CriteriaQuery criteriaQuery)  has 2 for loops , one for types and other for values. I get 2 types CustomType and LongType and so for each type it retrieves the value and adds it in the list in the order A00,A00,A00,1,2,5
