Ok, I think this is a bug. IClientHandle is not registered in the context so transient cannot be
used in the way it is documented (at least).
This is a bug IMHO and you should report it in trac under divmod.org.
But as I said the current version of livepage (which I think should be removed because buggy, not really working and not very supported lately) is not the main one.

Sessions are not in your control. Sessions are there for the server and not for the user. It's the
server that needs to distinguish between different requests from the users and not the developer.
Sessions are also a complete implementation detail (I mean the session object) because it could easily be just a string (although that would be impractical).
Adding/Removing stuff from something that you do not own is pretty risky and it's asking for trouble.

Not understanding the source of a problem is a clear sign of not being simple. Athena and livepage are similar in respect to difficulty and IMHO the americano way is a bit better.
