[ https://issues.redhat.com/browse/HIBERNATE-172?page=com.atlassian.jira.pl... ] nimo stephan updated HIBERNATE-172: ----------------------------------- Description: I have an orderinary entity with this property: {code:java} @Entity @DynamicUpdate public class User { private String name; @Convert(converter = TaskConverter.class) private Map<Task, Type> tasks; .. } {code} where the `Task` is an Enum-class and the `Type` is another Enum-class. The converter converts the tasks to a string and back. All works, however, Hibernate generates an additional update statement for the `tasks` when I create a new `User`-Instance or update other entity properties of the `User`-instance: {code:java} // this update statement is always created altough "tasks" was not changed update User set tasks=? where id_user=? {code} The above update statement always follows after another update statement of the same entity. For example: {code:java} // here I only change the name property and an update is triggered update User set name=? where id_user=? // but then hibernate also creates immediatly this update statement even if I did not change tasks update User set tasks=? where id_user=? {code} It behaves as if `tasks` would be an @ElementCollection where the `tasks` is always recreated on create or update of any other property within `User`. However, I annotated it with `@Convert`. Hibernate should not generate an update statement if `tasks` is left unchanged. was: I have an orderinary entity with this property: {code:java} @Entity @DynamicUpdate public class User { private String name; @Convert(converter = TaskConverter.class) private Map<Task, Type> tasks; .. } {code} where the `Task` is an Enum-class and the `Type` is another Enum-class.
