[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-5089) not-null integrity must be checked for DML statements and not for objects

not-null integrity must be checked for DML statements and not for objects ------------------------------------------------------------------------- Key: HHH-5089 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5089 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1 Environment: Windows XP Eclipse 3.5.1 Teneo 1.0.3 Reporter: Markus Bohr This issue somehow relates to HHH-4057 but is of much broader scope and pointing out a different aspect. Currently Hibernate checks the not-null constraint integrity persisting any object already on the object level (which is a quite early point in time; for loading objects, this might cause analoguous problems). The not-null XML attribute, however, is part of the <column> tag and therefore is assumed to match the characteristics of a column and not a mapped object property! I am facing severe problems with the current behaviour, as the not-null check is performed even before any nullSafePut() method is executed for a customized Hibernate type, or even before any the any PreInsertEventListener / PreUpdateEventListener has a chance to transform null-values for properties to non-null values for database columns. Effectively, the flexibility to handle different nullability characteristics between columns and their mapped properties is thus reduced to zero.
