Re: [rules-users] Changes made to knowledge bases and the time associated with it

Esteban, Is it commit'ed in any branch or tag maybe? I can only find 5.1M1. On a side note, come this weekend I'll start fiddling with drools source so I can solve the problem at hand. I'll let you know of any changes I make to the process of scanning directories and incremental changes.
