Re: [rules-users] Using multiple RuleFlows with similar group names
There is a loose coupling from the ruleflow-group defined in the drl and
the one in the ruleflow. So no matter how many rules you add, and how
they are added, there will only be one ruleflow-group "Group A". You can
deploy two ruleflows, both that use that group. The process that enters
that group first will then be in charge of executing the rules - you
should make sure there is no overlap in execution, I'm not sure what hte
behaviour would be then; i.e. the second ruleflow attempts to activate
the same group that the first ruleflow is already executing.

Hi,
I've built a RuleBase comprised of 2 ruleflows and their respective rules.
Each ruleflow is defined in a separate package however both use a common set
of ruleflow-group names. It looks something like this:
Ruleflows: Flow 1, Flow 2
Flow 1 package: com.test.flow1
Flow 1 ruleflow groups: Group A, Group B, Group C
Flow 2 package: com.test.flow2
Flow 2 ruleflow groups: Group A, Group B, Group C
When I load both packages into a RuleBase and insert an Object, I see that
rules in both Flow 1 and Flow 2 are executed, even though only ruleflow
process "Flow 1" was started. In short, it appears that Drools does not
take a rule's package into consideration when executing a ruleflow. Is this
expected behavior?
My understanding was that the rules in Flow 2 should not be executed because
they are in a different package.
I welcome any input.
