DerbyDialect is not backward compatible --------------------------------------- Key: HHH-6241 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6241 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.6 Environment: Latest Derby, Core 3.5.6 Reporter: Thomas Kratz Priority: Trivial I moved from 3.3.2 to 3.5.6 so I don't know when exactly this has been changed. In DerbyDialect there used to be the TableHiLoGenerator which is now commented out. When running on a DB that was created with SchemaGenerator from earlier releases the new Dialect gives ConstraintVialoations as the old ID columns are not of type identity. I could work around by sublassing DerbyDialect and implement the Genrator again. -- 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
