    Hi Michael

    Are you using trunk or MR2?
    There was a syntax change in trunk where the connective constraints were modified to || and && for consistency with the rest of the language.
    Also, I see a typo in the above rule where the variable name is "$pminp" but was written as "$pmin".

    Anyway, the exception message must be improved. Can you please add a JIRA with your test?

    Thanks once more,
       Edson

Hi,

I get a NPE (in v4.0) when loading a rulebase with the following rule:-

rule "smurf"
when
        $p1 : Property( $pminp : number )
        $p2 : Property( $pmaxp : number )
        $p3 : Property( $mlp : number < $pmin | > $pmaxp )
then
        System.out.println("The smurf has landed!" );
end

If the rule uses literals in the multi-restriction connective field constraint it loads OK.

The stack trace isn't very helpful:-

java.lang.NullPointerException
        at com.ford.finance.nges.rules.RuleEngineWrapper$WorkSpace.loadRulebaseFromDrl(RuleEngineWrapper.java :506)
        at com.ford.finance.nges.rules.RuleEngineWrapper$WorkSpace.loadRuleBase(RuleEngineWrapper.java:472 )
        at com.ford.finance.nges.rules.RuleEngineWrapper$WorkSpace.<init>(RuleEngineWrapper.java:64 )
        at com.ford.finance.nges.rules.RuleEngineWrapper.getWorkSpace(RuleEngineWrapper.java:582 )

Would you like a new JIRA?

With kind regards,

Mike
