[rules-users] RuleFlow only calling first RuleFlowGroup when called through drools-server

[Wolfgang Laun]

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.
