It's ok but you'll have to do a getHibernateTemplate().merge(blabla) or this : // delete all hibernate session objects this.session.clear(); // perform save getHibernateTemplate().save(blabla);
_____ De : Mel Pison [mailto:[EMAIL PROTECTED] Envoyé : lundi 10 septembre 2007 13:44 À : users@appfuse.dev.java.net Objet : [appfuse-user] Problem in updating an Object Hi all, I am using appfuse 1.9x and webwork as the web framework. I'm trying to build an application to manage studies but Im encountering some problems. The relationship of POJOs is like this, Study has many Studypageset(1 to many) and Studypageset has many studyPage (1 to many). I must create a Study object first before i could add studypage/s (equivalent to studies). Studypageset is for grouping of studypages for each studies. Now, I could add new studypages to studypageset and save it to its parent study but heres my problem whenever i edit then save a studypage in the different action i could get this kind of error: a different object with the same identifier value was already associated with the session: [com.voxsant.thinkscan.model.StudyPageSet#2]; nested exception is org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.voxsant.thinkscan.model.StudyPageSet#2] org.springframework.orm.hibernate3.HibernateSystemException: a different object with the same identifier value was already associated with the session: [com.voxsant.thinkscan.model.StudyPageSet#2]; nested exception is org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.voxsant.thinkscan.model.StudyPageSet#2] Caused by: org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.voxsant.thinkscan.model.StudyPageSet#2] I dont really know what could the possible errors here so pls help me. I also used session to save some of the attributes of the studypage because i cant placed it in a hidden field because it is an object reference. I dont if this approach is good... can you pls advice me some better practice here. sorry I am new to all these frameworks. kindest regards, Melchedick Pison
