MR2. The typo was my fault. Let me test in trunk (at home) before I raise a JIRA.

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.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?
