HI!

does someone else already had the Problem, that after an update, the table row is OK, but in my Object, it isn't updated? how can i solve that? do i have to call that explicit?

cheers

not enough info, but i may be a problem of java integrity (that is a code problem), are you using bidirectionnal association?

yes i use bidirectional assosiations.

a bidirectional many2many from contact to receiverlist. and we would like to get, that if i delete a contact, this should be deleted in all receiverlists. but not inverse. logicaly:-) do you need some more infos?

here some code:

contact.hbm.xml:

<class name="contact.Contact" table="contact">
<id name="contact_id" type="int" unsaved-value="null" >
<column name="contact_id" sql-type="integer" not-null="true"/>
<generator class="identity"/>
</id>
...
<many-to-one name="user" column="u_id" class="user.User"/>
<set name="receiverlists" table="consists_of" cascade="save-update" inverse="true">
<key column="contact_id"/>
<many-to-many class="receiverlist.Receiverlist" column="receiverlist_id"/>
</set>

</class>


receiverlist.hbm.xml


<class name="receiverlist.Receiverlist" table="receiverlist">
<id name="receiverlist_id" type="int" unsaved-value="null" >
<column name="receiverlist_id" sql-type="integer" not-null="true"/>
<generator class="identity"/>
</id>
...
<many-to-one name="user" column="u_id" class="user.User"/>

<set name="contacts" table="consists_of" cascade="save-update" >
<key column="receiverlist_id"/>
<many-to-many class="contact.Contact" column="contact_id" />
</set>

</class>



the file where we would like to delete a contact :...and i'm sure, its not that f. complicated....:-)
with this file we have to delete the deleted contact in the receiverlists. but i think that should be done automatically by hibernate...



public class DeleteContactAction extends Action{

public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest req, HttpServletResponse res) throws Exception{

List temp = Collections.synchronizedList(new ArrayList());
DynaActionForm df = (DynaActionForm)form;
String[] contactId = (String[])df.get("deleteContact");
HttpSession session = req.getSession(true);
User user = (User)session.getAttribute("user");

for(int i=0; i < contactId.length; i++){
Set contactSet = user.getContacts();
Iterator contactIter = contactSet.iterator();

for(int m=0; m < contactSet.size(); m++){
Contact contact = (Contact)contactIter.next();
if(contact.getContactId() == Integer.parseInt(contactId[i])){
Deleter.delete(contact);
temp.add(contact);
}
}
}


Iterator tempIter = temp.iterator();
for(int n = 0; n < temp.size(); n++){
Contact c = (Contact)tempIter.next();
user.getContacts().remove(c);
Set receiverlistSet = user.getReceiverlists();
Iterator receiverlistIter = receiverlistSet.iterator();
for(int r=0; r < receiverlistSet.size(); r++){
Receiverlist receiverlist = (Receiverlist)receiverlistIter.next();
receiverlist.getContacts().remove(c);
}
}

return mapping.findForward("contactDeleted");
}
}

you have to manage both ends of the association.
For this, the best practice is to have removeChild and addChidl methods in which you set the parent and the child ends of the association.
If you have hibernate in action, it is very well explained
