Hello thanks for the quick and precise answer!
I believe that the time difference will be a bit of a problem for the IRC
chat , but i will be online (channel: #drools user: igrachev) today and will
try to check it often. However big thanks for the support and the willingness
to help!
You are saying that the code is there, but is not public and documented. Well
being not public seems to be a problem, but do you think it is possible to
give me an example with the official Drools "first rule" - Sample.drl. The one
that comes with the first Drools project. So do you believe it will be
possible to paste me some code on how to retrieve the information that this
ruleset is using one fact of type Message and two of it's attributes - status
and message. So just some code in a public static void main (String [] args)
will be great :), or any kind of explanation :).
Once again thank you.
Have a nice day,
Milen

The code is there, but it’s not public and not documented, and the code can be
a little hard to understand - as it’s grown organically over the years.
You’ll need to cast and unwrap and look at member vars. Start on the Rule and
the lhs variable. You can always pop onto irc, with live questions,and we’ll
try and respond quickly.
