For the last couple of days I get the MatchErro on boot of ESME (see below for full stack trace).

I guess this is related to the following commit, although I verified that dchenbecker's fix on 20 July is updated on my system, and the error persists:

http://groups.google.com/group/liftweb/browse_thread/thread/722c75462e400a4c

We are using Lift 1.1-SNAPSHOT. This is ESME constructs the index:

override def dbIndexes = Index(user, message) :: super.dbIndexes

Full stack trace follows:
