[rules-dev] Re: [rules-users] Problem with update(fact)

[Edson Tirelli]

   Felipe,

   Thanks. I'm working on it.

   BTW, I forgot to mention, what you are doing to control rules is a not a
good way to do it. You should try agenda-group+lock-on-active rule
attributes instead.
   Look at the conway's game of life as an example, and maybe help us
document the feature... :)
