Hi, We migrated our project from Drools 3 to Drools 4. We observed a slight change of behavior in execution of rules in sequential mode. Suppose we have drl file with two rules. In first rule we find whether customer is preferred customer or not and in second rule we use it to set a discount percentage (portion of drl provided below). In Drools 3 if we use sequential execution using rulebase.addPackage(pkg,false) then both the rules get fired (because first rule updates customer object). But in Drools 4 if we use sequential execution (using ruleBaseConf.setSequential(true)) then rule "preferred" gets fired but rule "discount" doesn't. Apparently the update() in first rule does not take effect. This is not the behavior one would expect. Is there any configuration by which same behavior can be achieved for Drools 4 also? I went through the user guide and tried few things like setting ruleBaseConf.setSequentialAgenda(SequentialAgenda.DYNAMIC) (and SequentialAgenda.SEQUENTIAL too) but nothing worked. rule "preferred" no-loop true salience 999999 when customer:Customer() eval(customer.getMonthlySalary() > 5000) then customer.setType(Customer.PREFERRED); System.out.println("Updated customer type."); update(customer); end rule "discount" no-loop true salience 999998 when customer:Customer() eval ( customer.getType().equals(Customer.PREFERRED) ) then customer.setDiscount(20); System.out.println("Updated discount percentage."); update(customer); end Regards, Mohit ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!
