Hello, i had similar problems with or constructs, and decided to avoid them.<div>Drools expert manual says that or constructs are internally rewritten, i suppose this mechanism is not fine-tuned.</div><div>My 2 cents...</div>

Hello.<br>
<br>
I have a problem with such a condition after 'when':<br>
(or (and MyFact(id==1) MyFact(id==2)) (or MyFact(id==3) MyFact(id==4)))<br>
<br>
For this condition I got this error:<br>
errors; [7,41]: [ERR 101] Line 7:41 no viable alternative at input 'or'<br>
in rule "Sensor-1-ON"[7,64]: [ERR 102] Line 7:64 mismatched input<br>
'MyFact' expecting ')' in rule "Sensor-1-ON"[7,84]: [ERR 102] Line 7:84<br>
mismatched input ')' expecting 'then' in rule "Sensor-1-ON"<br>
<br>
When I changed my condition to this:<br>
(or (and MyFact(id==1) MyFact(id==2)) MyFact(id==3) MyFact(id==4))<br>
everything is correct. Both conditions from logic point of view, are the<br>
same, but the first one can't be compiled. Why?<br>
<br>
Maybe someone had similar problem and could help me?<br>
<br>
I'm using:<br>
* JBoss <a href="http://4.2.3.GA" target="_blank">4.2.3.GA</a><br>
* Drools 5.0<br>
<br>
Regards,<br>
Piotr<br>
