[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1152?page=c... ] Stefan Fromm commented on HHH-1152: ----------------------------------- I'm trying to implement the Role Object Pattern for domain objects. I would need component inheritance for the role objects. Treating them as entities is not possible, because they appear to be the same object as their core object - they have the same identity. Adding more than 1 role object to the core object results in a NonUniqueObjectException. I have to change back my domain model to the Extension Object Pattern where the extension/role objects are not identical to their core object. I agree with Ilya. "table per class hierarchy" would suffice initially. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
