@Mark
thanks, it works when adding any other qualifier!
btw, do you think it would hurt to qualify the built-in conversation bean with
@Named("javax.enterprise.context.conversation") in OWB? That way I could inject
the built-in with @Inject @Named("javax.enteprise.context.conversation") and
expose it via @Produces @Named("conversation") without resorting to some extra
qualifier.
@Romain
I was wondering where exactly is your hacky el resolver implemented? If the
"javax.enterprise.context.conversation" name is a requirement coming from the
CDI spec, then I would suppose it is implemented in OWB (in the resolver you
get from the BeanManager) but as my tests with OEJB+OWB fail, I suppose it is
not there (or not enabled in some way). On the contrary, if the requirement
comes from the java EE spec, then I suppose it is implemented in TomEE and that
would explain why my tests fail.

Subject: Re: OpenEJB and EL
@Default is always assumed when you don't add a specific Qualifier other than
@Named and @Any.
Xavier, can you please add any random qualifier? E.g. @Destroyed.
This will stop CDI from complaining but EL should work.
