[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-1596) Unique Constraint Validator

[ http://jira.jboss.com/jira/browse/JBSEAM-1596?page=comments#action_12368559 ] Christian Bauer commented on JBSEAM-1596: ----------------------------------------- "Currently, if a column is unique, we get a exception, which doesn't make it possible to tell a user which field is not unique: It would be nice if we get an InvalidStateException, which can be cleanly reported. " Uhm, you are supposed to _CHECK_ before you _INSERT_. You are not supposed to throw random data in the direction of your database and then "report" if something fails. This is what this issue is about, whether Seam should over built-in procedures for this check or not. I agree with Emmanuel that it shouldn't, because avoiding race conditions would require locking between check and insert, and that should really be up to the developer. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
