15. Re: Who uses EntityHome objects?
My problem is to specify the id of an object. But i have realized, that the possibility to set the id in components.xml is no more there. With or without namespaces.
huh, why do you say that? use -

17. Re: Who uses EntityHome objects?
Finally i got it.
<pages> <page view-id="/search.xhtml"> <param name="accountId" value="#{accountHome.id}" converterId="javax.faces.Long" /> </page> </pages>
This means that the value of the accountId parameter will be set to the Id of accountHome. This part was not obvious to me.:-(
And The value of the accountHome id will be remembered in the parameter. This comes out very clearly from the docs.

18. Re: Who uses EntityHome objects?
I'm having the same problem, I'm starting with seam, using EntityHome, and as far as I understand that only propagates the parameter to the page, still has to be injected, I use
@RequestParameter Long userId ;
however my source is nearly identical to the one in the exaples of reference documentation (started from seam-hotel-booking and extended it) and form always shows "Create" buttons, id is not being propagated, or EntityHome is not properly configured, I'm lost. I cannot update/delete wich was the main reason on using EntityHome. If I actually pess submit button to new #{userHome.persist} I get the following:java.lang.IllegalStateException: No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)
Apparently some validation assigned null variables where @NotNull fields were.
... is there any working EntityHome example ? searched examples dir for "EntityHome" and no strings were found. -

For a working example, see examples/contactlist, or simply generate an application using "seam setup new-project generate-entities".

20. Home Entity not partially working
... finally managed to use EntitiHome in my project, however this code works:
<factory name="user" value="#{userHome.instance}"/> <framework:entity-home name="userHome" entity-class="myPackage.User" entity-manager="#{entityManager}" />
while this one does not:@Name("userHome") @Scope(ScopeType.CONVERSATION) public class UserHome extends EntityHome<User> { @In EntityManager entityManager ; @RequestParameter Long userId ; @Factory("user") public User initUser() { return getInstance() ; } @End public String persist() { super.persist() ; return "users" ; } @End public String update() { setId( userId ) ; super.update() ; return "users" ; } @End public String remove() { setId( userId ) ; super.remove() ; return "users" ; } @Destroy @Remove public void destroy() {} }
... is this a bug ? or am I missing something ? I believe it's better to use inheritance to add some extra features by hand, but I can't :( -

22. Re: Who uses EntityHome objects?
From the documents, you can see that the right way is to override the getId(). But it isn't correct to setId for the update() or remove()
