[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4552) Support generated value within composite keys

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4552?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34675#action_34675 ] 

Steve Ebersole commented on HHH-4552:
-------------------------------------

Paul, maybe an example is the best description...

Consider a component:
{code}
public class EmployeePK {
    private String payrollNumber;
    private String departmentCode;
}
{code}

HHH-2060 is about allowing to define a generator which constructs and returns EmployeePK instances.

HHH-4552 (this issue) is about allowing to define a generator for the individual properties in a composite identifier.  So for example, to say that "payrollNumber" is generated by some generator.  This is needed because of the SpecJ committee, retards that they seem to be, and how they mis-interpret the JPA2 spec because it does not explicitly disallow doing this.

> To ensure compatibility/portability with other jpa implementations hibernate need support for generated value for composite keys. The SpecjEnterprise2010 application require this.
