Bug 319759 - ChangedFieldsLockingPolicy fails for update queries
resetting a null value to a non-null value https://bugs.eclipse.org/bugs/show_bug.cgi?id=319759 Description: With some OptimisticLockingPolicies configured, executing cached update calls can fail when cached calls are re-executed with non-null values. Fix: internally set a flag on DatabaseQuery from the various OptimisticLockingPolicy implementations when performing updates, as well as set a flag on the AbstractRecord when a null field value is encountered). The flags then determine whether the update call cache can be used for a particular query and translation row. Testing: LRG, JPA LRG on Oracle & MySQL New tests: New model in OptimisticLockingTestModel, several new tests Reviewed: Gordon Yorke Fixed in revision: 8130 --
