|| in conditional element causes exception
------------------------------------------
Key: JBRULES-1558
URL: http://jira.jboss.com/jira/browse/JBRULES-1558
Project: JBoss Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Reteoo
Affects Versions: 4.0.4
Reporter: Juraj Bednar
Assigned To: Mark Proctor
Priority: Minor
rule "testRule"
dialect "mvel"
when
$m : TestFact ( booleanTest == true && (number <= 100 || number >=
(anotherNumber * 2)))
then
System.out.println("Error");
end
("&&" can be also replaced by "," having the same effect)
This rule compiles well and in runtime, when booleanTest becomes true, it creates this
Runtime exception:

The syntax is OK according to documentation:
-----
It is possible to change the evaluation priority by using parenthesis, as in any logic or
mathematical expression. Example:
Example 6.10. Using parenthesis to change evaluation priority
# Cheese type is stilton and ( price is less than 20 or age is mature ).
Cheese( type == "stilton" && ( price < 20 || age ==
"mature" ) )
