[hibernate-issues] [Hibernate-JIRA] Created: (ANN-669) More then one @Id silently fail

More then one @Id silently fail ------------------------------- Key: ANN-669 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-669 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.0.ga Environment: Hibernate 3.2.5, MySQL Reporter: Hontvári József Priority: Minor If two fields have @Id and the class has no @IdClass annotation then the first(?) field will disappear from Hibernate metadata. I.e. you will see in the log in a "EntityLoader Static select for entity..." entry that the select doesn't contain the field. (If you add an @IdClass or leaves only one @Id annotation makes the column appear again.) The first problem is that is doesn't say anything, even on trace logging level, it just fails in a strange way. The second is that I belive the @IdClass shouldn't be required anyway. There is a similar construct in the xml mapping using the composite-id element: if no primary key class is supplied then the entity class itself become the key class. This is not as rude as it seems, just imagine a class of which all attributes are part of the primary key. -- 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
