[rules-users] NPE loading rule with multi restriction connective field constraints

[Anstis, Michael (M.)]

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$WorkSpace.loadRulebaseFrom
Drl(RuleEngineWrapper.java:506)
	at
com.ford.finance.nges.rules.RuleEngineWrapper$WorkSpace.loadRuleBase(Rul
eEngineWrapper.java:472)
	at
com.ford.finance.nges.rules.RuleEngineWrapper$WorkSpace.<init>(RuleEngin
eWrapper.java:64)
	at
com.ford.finance.nges.rules.RuleEngineWrapper.getWorkSpace(RuleEngineWra
pper.java:582)

Would you like a new JIRA?

With kind regards,

Mike
