[rules-users] How to run an agenda group multiple times?

[Wolfgang Laun]

Consider this scenario:
  insert facts, rules r, s, t in group G are activated
  set focus for agenda group G
  set focus for agenda group G
  fireAllRules
  rules r, s fire
  rule t fires and inserts a fact so that rule u in G is activated
  rule u fires
  G is popped from the stack - no more rules in G are activated
  G is popped from the stack - no rules in G are activated

Two immediately successive pushes of the same agenda group are useless.
