Re: removing a child from 1:n [SOLVED] [WORKING]

[Joose Vettenranta <jo...@iki.fi>]

I just wanted to say, that I got it to work.. I did it so, that in the  
Child i made delete -variable which is checked on update-action (not  
very good if there is million child).

So my DAO.update() is like this now:

         public void update(Parent bean, JdoPMF pmf) {
                 PersistenceManager persistenceManager =  
pmf.getPersistenceManager();
                 PersistenceBroker broker =  
PersistenceBrokerFactory.defaultPersistenceBroker();
                 Iterator it = bean.getChilds().iterator();

                 broker.beginTransaction();
                 while (it.hasNext()) {
                         Child child = it.next();
                         if (child.getDelete()) {
                                 broker.delete(child);
                                 it.remove();
                         }
                 }
                 broker.store(bean,  
ObjectModificationDefaultImpl.UPDATE);
                 broker.commitTransaction();
                 broker.close();
         }

and it works.

Thanks,

Joose
