Hi, I am currently using JBoss Rules 4.0 and need help with the OR operator. The rules look similar to the following: rule "rule1" (Field (ID == 1, strValue matches "test") and Field (ID == 2, lookupValue contains 7337 || lookupValue contains 3901) and Field (ID == 3, dateValue >= "04-Jul-2000")) or (Field (ID == 4, strValue == "foo")) then System.out.println("rule fired"); end The rules are constructed with data from UI and there can be multiple nesting of OR and AND operators. As mentioned in the documentation and earlier postings, the expected behavior is that this rule fires twice if both the 1st and 2nd halves of the OR operator are true. As per our requirement, the 2nd half of OR should be evaluated only if the 1st half is false. So that way the rule can fire only once. I do not want to retract the inserted objects as I want other rules to fire too. How can I write this rule to get the required behavior? Thank you.
