[rules-users] Accessing rule flow names

To do testing, I have an event listener that keeps track of which nodes have been activated, etc. by accessing the ProcessNodeEvent where I can either get the NodeID or the NodeName, but cannot get the associated rule flow. The NodeID appears to be numeric and always automatically assigned, so perhaps I should be tracking these values, but I had hoped to keep track of which RuleFlowGroup was activated. Is there a way to access this variable? Thanks. - Mike
