Hi container developers!
The most important part first, the server trace (client trace says
nothing new):
jBoss: [User] [15] getPersonalDetails(15,null)
jBoss: [UserACL] [15acl] hasAccess(15,null)
jBoss: [UserACL] [15acl] isOwner(15,null)

Ok, that is what is going on inside the code:
User.getPersonalDetails() is called from the client. The B2B reference
to UserPersonalDetails is still null at this time. GetPersonalDetails()
checks the null value after some access right checking with UserACL and
creates a new UserPersonalDetails bean. This bean itself creates a new
UserACL object. In the database I can see, that the UserPersonalDetails
object stored the reference to the new UserACL bean. But the User bean
does not store the reference to the new UserPersonalDetails bean.
Ok :-) , try this one:
User UserACL(for User) UserPersonalDetails UserACL(for UserP.D.)
|
getPersonalDetails()
------------->|
some checking
|<------------|
discovers
B2B reference
is null
|-------------------------------->|
create()
|----------------->|
create()
|<-----------------|
(reference to
UserACL stored)
CONTAINER EXCEPTION?
CONTAINER EXCEPTION? <------------|
And, I am afraid, I am working with the latest cvs checkout.
Please HELP !
Which additional information do you need ?
Ciao,
Tobias
