<div>Using Drools Expert 5.0.1</div>
<div> </div>
<div>The following rule fires both when the “not” is there, and also if the “not” is commented out. Clearly, both cannot be true, so there is something wrong somewhere.</div>
<div> </div>
<div>I’ve narrowed it down to the testing of the $parentEmploymentId declaration – the AccountHolder CE, which is inside the context of the “not”, is referencing $parentEmploymentId, which is declared outside the “not”.</div>
<div>If the indicated line is commented out, then the expression behaves sensibly (i.e. fires either when the “not” is used, or when it isn’t, but not both). However, an important business semantic element is then missing from the rule.</div>
<div> </div>
<div>Is this a bug in Drools, or am I misusing something?</div>
