Hi all, I am using /OptaPlanner/ ver. *6.0.Beta3*. And I try to call one rule for preparation purposes. I try 3 options: *1)* By defining additional problem facts /EmployeeAssignment/ for each employee. Here I am trying to change only its property like this: /rule "First rule" salience 1 when $employeeAssignment : EmployeeAssignment($employee : employee) accumulate ( $request : Request(assignedTo == $employee, $points : points), $assignedPoints : sum($points) ) then $employeeAssignment.setAssignedPoints($assignedPoints.intValue()); update($employeeAssignment); end/ That variant compiles well, but did not even start (e.g. when I try benchmark it stops on "Warming up started" message and did not do anything). *2)* Same with /modify($employeeAssignment) {...}/ *3)* The last one is with /insertLogical/. I did not use here /EmployeeAssignment/ as additional problem fatcs, but just use: /then insertLogical(new EmployeeAssignment($employee, $assignedRequests, $assignedPoints.intValue())); end/ It works, but with low performance (examples were simplified). Can you tell me what can be wrong with the 1) and 2) ? Thank you for your time! -- View this message in context: http://drools.46999.n3.nabble.com/modify-and-update-do-not-work-in-rules-...
