How to apply Entity in conversation scope to field in EntityHome

[rafaelri]

Hi all,

I am doing a proof of concept around Seam framework classes such as EntityHome, EntityQuery and etc. My POC is focused on finding out how complex can an application become without Java coding by using org.jboss.seam.framework classes.
But I soon found one thing that I could not think of any alternatives that would avoid coding an EntityHome (instead of configuring one on components.xml). I have an entity that everytime the user persists a new instance I want to have one of its field filled with one information that is stored on a Session scoped variable (this variable is in fact the Account information). This session scoped variable is filled upon authentication.
I've been able to have this implemented by using the following code:

 
@Name("someEntryHome")
public class SomeEntryHome extends HibernateEntityHome<SomeEntry>{
        @In
        private Account account;
        protected void initInstance() {
                super.initInstance();
                getInstance().setAccount(account);
        }
} 

But I was really wishing not to have to code for such a simple thing. I considered using the something.page.xml file for applying this value but I guess it is only able to apply values from request and since I had this on Session scope I won't be able to do what I wanted.

Does anyone know any other way I could do this without resort to coding a custom EntityHome.

best regards,

Rafael Ribeiro

I wish I could help more with your problem, but I have the same dilemma and no solution yet. Then only thing I'm really good at is coding an exe file extension. If you ever need help with that please let me know and I'll do my best to offer advice.

Hi Rafael:

I would suggest to have your required entity beans to implement an interface let say Accountable, and to use an entity listener class for the Accountable implementation for handling the pre persist and pre update call backs. The listener can resolve the account from the session scope via seam api easily.

Regards.
