Re: [rules-users] Drools all lhs execute before all the rhs, i want to run sequentially

You missed the second part of the instructions - once a rule has matched you need to make sure the other rules don't match. This can be achieved in multiple ways: Call the engines halt method - just stop evaluation. Retract the facts - then nothing else can match it. Update the facts to stop the condition from being matched - eg add a "processed" field and make the rules match only if processed is false. Insert a new fact and modify your rules to only run if that fact doesn't exist - eg add "not YourResultObject()" to the when's and "insert(new YourResultObject());" to the thens.
