Sanjay,
Yes, I'm looking into this, I managed to reproduce a problem with
restoring the session. Not the exact same problem though, but similar,
so I guess that's because I'm using the latest trunk. I need to get
some help from Mark or Edson on this one (as it's really related to the
rule internals), and will get back to you asap.
