I'm using the chenillekit hibernate daos, and there is no explicit update
method, so i thought save() should do this job.
I don't understand why there is a new Object if I annotade the config with
@Persist. Shouldn't it be saved in the Session?
btw: i found a possible solution with page activation context:
void onActivate(Long configId){
config=configDAO.doRetrieve(configId,false);
}
Long onPassivate(){
return config.getId();
}
but I still want to know why it won't work with @Persist?

Betreff: Re: Updating Hibernate Entites
You are trying to save a new object while using the old object id ,
what would end in two entities with same id - something not possible.
You should call your DAO update method , instead of save.
