Description
Given the following rule:
global java.util.Set controlSet; global org.example.drools.service.DummyService dummyService; declare A x: String end rule "will execute per each Measurement having ID color" no-loop when $m: Measurement( id == "color", $colorVal : val ) $a: A() String() from dummyService.dummy($m.getSomethingBy($a.x), $a) then controlSet.add($colorVal); end
The compilation fails with:
