[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2460) Multiple object creates on HQL select causes "unexpected token: , "

[Jesse Sweetland (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2460?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=40164#action_40164 ] 

Jesse Sweetland commented on HHH-2460:
--------------------------------------

EJB3 Persistence spec states in section 4.14 (EJB-QL BNF definition) that a select_clause is one or more select_expressions separated by commas, and a select_expression can be a constructor_expression.  This seems to indicate that this syntax is valid (per spec) and that this is a legitimate issue.
