Rolling back vs deleteobject

[Marek Šabo]

Hi all,

I would like to know your opininon on this (example adding user):
 try {
            getObjectContext().commitChanges();
            return user;
        } catch (CayenneRuntimeException cre) {
            //getObjectContext().deleteObject(u);
            getObjectContext().rollbackChanges();
        }

I was using deleteObject method but that didn't reccure so foreign key 
objects were left just like that in context, rollback does the trick for 
me. I'm not sure how exactly this rollback works when I'm using 
getThreadObjectContext - will it be unique for every user session on 
webserver?? I hope it's not shared amongst them. And what's the 
difference from the "local" version of rollback?

Thanks in advance,

regards,

Marek
