Re: [rules-users] Rule problem

Femke, The "Overgewicht| rule matches for _two_ BMIClass facts, one with bmi >- 25 and one for BMIClass <30. If you want to apply multiple constraints to a single fact you have to list them as such: > rule "Overgewicht" > when > bmiClass : BMIClass(bmi >= 25 && bmi <30) > then > System.out.println("U heeft overgewicht"); > end Cheers, Ingomar Am 04.05.2009 um 00:48 schrieb Femke De Backere: > Hi! > > I want to make en BMI rule application, so I need to test the BMI > values.
