Re: [rules-users] RuleFlow only calling first RuleFlowGroup when called through drools-server
Activating and deactivating rules in batches (i.e., groups of one sort
or other) cannot be imitated by salience.
If you leave a group, no rule from that group stands a chance to
become active again. But a high-salience rule that isn't activated
before 0:12:34.567 may (after some firings of low-salience rules)
become activated at 0:12:34.567, after its LHS has finally made the
match point.
I have used agenda groups to achieve a flow of rule batches --- no
problem in 5.1.

I decided to try using salience instead of RuleFlow to try to control the
order in which the rules fire. It is not ideal, but I thought I could get it
to work. However, I am seeing rules with higher salience firing after rules
with much lower salience. It doesn't consistently happen, but it seems that
salience is not very reliable across a large number of rules.
Still curious to know if there are plans to address the above issues (2718)
in 5.1.1. It seems like this is fairly important functionality.
