T5 IoC: Alias service's mode

[Joshua Jackson <jo...@gmail.com>]

Dear all,

Where do I setup Alias service's mode for  a module?

I received this error when trying the T5 tapestry-hibernate module:

Here's how I tested the tapestry-hibernate module:

>         RegistryBuilder builder = new RegistryBuilder();
>
>         builder.add(TapestryModule.class);
>         builder.add(HibernateModule.class);
>
>
>         Registry registry = builder.build();
>
>         HibernateSessionManager manager = registry.getService(
> HibernateSessionManager.class);


When I checked the HibernateModule class, it already setup an Alias. Do we
need to set it up again? I don't have any clue on this. What have I missed
and done wrong? Can anyone give me a hint.

Thanks in advance
