             Summary: Allow bound variables to be a function of 3 and 4 other variables
                 Key: DROOLS-4911
                 URL: https://issues.redhat.com/browse/DROOLS-4911
             Project: Drools
          Issue Type: Enhancement
          Components: executable model
    Affects Versions: 7.31.0.Final
            Reporter: Lukáš Petrovický
            Assignee: Lukáš Petrovický
             Fix For: 7.32.0.Final


For a use case in OptaPlanner's Constraint Streams (see PLANNER-1764), I need to be able to call variable binding functions with 3 or 4 arguments. This will allow me to handle cases like this:

{noformat}
$p1: Person()
$p2: Person()
$p3: Person($allMoney: $p1.money + $p2.money + $p3.money)
{noformat}

At the moment, Drools exec model only supports cases of up to 2 arguments. I need to bring the number up to 4.

I do not plan to introduce this functionality into DRL, as my use case leverages exec model directly.
