[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4075) UnsupportedOperationException when assigning an alias to an indexed collection

UnsupportedOperationException when assigning an alias to an indexed collection ------------------------------------------------------------------------------ Key: HHH-4075 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4075 Project: Hibernate Core Issue Type: Bug Components: query-hql Affects Versions: 3.3.2 Environment: Hibernate 3.3.2.GA, MySQL5InnoDBDialect Reporter: Robert Wruck This works: select count(*) from Order o left join o.orderAttributes oa, Attribute a where a.id = 1 and index(oa) = a but accessing elements throws an exception: select count(*) from Order o left join o.orderAttributes oa, Attribute a where a.id = 1 and oa[a] is null or oa[a] = '2' Replacing oa[a] with o.orderAttributes[a] does not throw an exception but also does an inner join, so it's not a workaround.
