Subject: Ruleflow-group attribute causing rule to not fire

Hi,

 

I am new to both rules engine and Drools. I am currently evaluating Drools 4.0.7 for use in our new project.

Basically I have been writing a bunch of individual rules and things have been fine, the rules that I expected to fire were fired, etc, etc. I then proceeded to investigate rule flows. I started innocently enough i.e. adding the ruleflow-group attribute to some of my rules. I also defined a ruleflow mapping (.rfm).

 

I then reran my unit-tests (WITHOUT reading the rules in as rule flows) and some of my rules were no longer firing!!. I added an Agenda Listener to my code and

1. without the ruleflow-group attribute, activations were created, and fired.

2. with the ruleflow-group attribute, activations were created but not fired.

 

Using the debugger yielded the same logical outcomes i.e. without the ruleflow-group attribute, my breakpoints were hit, but with the attribute specified, none of my breakpoints were hit.

 

My question is: Is this behavior expected? And why? Especially since some other rules (with the attribute specified) continued to work. I've read the documentations as much as possible, but I am really new to this field so I might not even know what questions to ask either.

 

Any help would be greatly appreciated.

 

Thanks,

 

Roger
