    [ https://jira.jboss.org/jira/browse/EJBTHREE-508?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12456908#action_12456908 ] 

Xiaolong Hao commented on EJBTHREE-508:
---------------------------------------

if possible can we re-visit this issue? We do have a case that we need a composite key with one surrogate field and one for db schema so that we can access same functional table in different schema. Plus,
hibernate is handling it in xml configuration. HHH-2060.

> I have an entity with a primary key class (@IdClass annotation) where i want the id to be auto-generated. (see forum post)
> That does not happen though, no ids are generated, the only id i get is 0. (leads to one database entry where the id is 0, after that errors of course). 
> Database is Hypersonic SQL.
> The entity works perfectly fine without @IdClass annotation.
