This is expected behaviour, let me try to explain.
By adding the ruleflow-group attribute to your rules, you are stating that
these rule should not be executed as normal, but that the order in which
these rules should be executed is specified by a ruleflow. Activations will
be created for rules that are part of a ruleflow-group, but they will only
be executed if the ruleflow-group is activated. To make sure that rules with
a ruleflow-group are executed, you must:
1. Create a ruleflow that specifies when the rules should be activated
(using ruleset nodes)
2. Start the ruleflow whenever appropriate. My guess is that you are not
starting the ruleflow, so the corresponding ruleflow-groups are never
activated. You can either start a ruleflow manually in your code
(workingMemory.startProcess("id_of_your_ruleflow"), for example right before
calling workingMemory.fireAllRules()), or using a rule (probably with a high
salience) with as consequence
It is also normal that all other rules that are not tagged with a
ruleflow-group attribute just execute as before, even in the presence of
ruleflows, both can be used side by side.
