Hello, - I have a set of rules attached to a workflow using the ruleflow-group attribute. I'd like to reuse these rules in another context outside the workflow. What's the best solution to do this? - I tried to use rules inheritance with the extends keywords but this solution is not working as the RHS of the base rule is not executed. More over, it is not very convenient as new rules have to be created and maintained. - Here is a very simple example to illustrate my problem: I'd like to reuse this rule outside my workflow: rule "firstNameIsEmpty" ruleflow-group "validate-person" when Person(firstName == null || firstName == "") then System.out.println("ERROR : Empty first name"); end One possible solution would be to create one base rule that could be reused outside the workflow: rule "firstNameIsEmpty" when Person(firstName == null || firstName == "") then System.out.println("ERROR : Empty first name"); end and another rule for the workflow: rule "firstNameIsEmptyInRuleFlowGroup" extends "firstNameIsEmpty" ruleflow-group "validate-person" when then end But, in this case, the RHS of the base class (System.out) is not executed. Is there another solution to solve this problem? Thanks -- View this message in context: http://drools.46999.n3.nabble.com/Reusing-rules-outside-a-workflow-tp2919...
