Hello,

Silly newbie question.  I'm trying to write my first rule set to handle permissions and I'm running into a problem where Drools is not executing the 'then' clause of all my rules, even though they all resolve to true.

Here's my sample file:

rule "Docs1"
        activation-group "permissions"
        no-loop true
        when
                Resources( $resList : resourceList )
                $res : Resource(name=="CUSTOMER", allowed==false) from $resList
        then
                System.out.println("Foo");
end

rule "Docs2"
        activation-group "permissions"
        no-loop true
        when
                Resources( $resList : resourceList )
                $res : Resource(name=="INVOICES", allowed==false) from $resList
        then
                System.out.println("Wow");
end

I'm using a StatelessKnowledgeSession something like this:

        ArrayList ruleObjs = new ArrayList();
        ruleObjs.add(resources);
        kbase.newStatelessKnowledgeSession().execute(ruleObjs);

So here's my problem.  Both of the rules above resolve to true.  But only "Wow" is output to the console.  If I comment out the Docs2 rule entirely then "Foo" is output to the console (proving it also resolves true).

Why wouldn't I get "Wow" and "Foo" output to the console (in no particular order) when both are run?  

To see whether both rules are actually being evaluated I also tried creating a simple message function that prints something to the console and returning true. Then I eval() my function as the last line of the when clause in Docs1.  "Wow" from Docs2 is output as before, as is my function's message (proving that Docs1 was evaluated and resolved truthfully), but... Docs1 'then' clause is not executed and Foo is not output.  Why?

This scenario holds true if I have lots of rules.  Only the 'then' clause of last one resolved true is executed even though there may have been several other rules that resolved true.

Thanks in advance for any ideas or help!

Best regards,
Greg
