At issue, the rules within the second ruleflow, though activated, are
not
being executed.
Do you have a test case that shows this behaviour? If you open a JIRA and
attach the test case, I'll take a look. Have you tried starting the process
directly using the startProcess method on the working memory directly? Does
this change the situation? In theory, there should be no difference in
starting a process, no matter how you start it. And ruleflow groups should
only deactivate if there are no more activated rules in the ruleflow group.
