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.
