[rules-users] Rule error

[Vincent Legendre]

Don't put that in a eval, but directly in the second pattern 
constraints, like this :

rule "ValidMechanism"
	when
		$c : Capacity(doMin>20)
		$m : Mechanism(*doMin<= $c.doMin,*
  DMOMax<=30, doMax>50&&  doMin<40&&  maxPower>180&&
minPower>=100&&  bidPower>100&&  <200)
	then
		System.out.println("Capacity n°"+$c.getIdCapacity()+" eligible to the
mechanism n°"+$m.getIdMechanism()+" for rule 1" );
end
