Hello, i have the following problem. i have a table "projects" and a table "managers" with a i think called "1:N" relationship. My mapping file (partly): <hibernate-mapping> <class name="....Project" table="Project"> <set name="managers" inverse="true" cascade="all"> <key> <column name="Projectid" not-null="true" /> </key> <one-to-many class=".....Manager" /> </set> </class> </hibernate-mapping> Now i want to delete all my managers concerning one special project and add the new manager. So I do the following: Manager manager; ProjectDAO dao = new ProjectDAO(); Project project = (Project) dao.getSession().get(Project.class, projectID); Set managers = project.getManagers(); managers.clear(); manager = new Manager(); manager.setEmployee(employee_manager); manager.setFunction(managerFunction); manager.setProject(project); dao.getSession().save(manager); managers.add(manager); project.setManagers(managers); dao.save(project); But the thing is that only the new manager was added. The other database entries were not deleted. I thought, if i update the parent entry (project) the child entrys will be deleted automatically (project.getManagers.clear()). Where is my problem? Can anybody help? Thank you very much!!! Greetings from Berlin! Ingo |
