You could make a PersonRPC class that contains only the fields you want to
pass to the client...
You could also make PersonRPC the parent class of your Person class.

Hi,
I read a lot of time that flex/blazeds/hibernate is a cool combo. But
I there is one thing that troubles me.
So let's asume I have a Person class
public class Person {
public var name:String;
public var id;
}
It's no problem to send objects from this class between client and server.
But let's assume the Person class has furthermore a list of groups he
belongs to.
public class Person {
public var name:String
public var id;
public var groups:ArrayCollection;
}
public class Group {
public var name:String;
public var id;
}
So now everytime we send a person object back to the blazeds/hibernate
backend all the groups he belongs to are getting serialized as well.
This means a lot of overhead gets send to backend when I only modify
some primitve data like the name.
Even more problematic would be if in addition the group objects
themselves would have list of persons that belongs to them.
I guess I could use the [Transient] Metatag to not send the collection
fields, but then I could not modify the groups in a person object easily.
So if there is any best practice for these kind of problems, please
let me know.
Thanks in advance
Max
