      Description

      Given the following rule:

      import java.util.Map;
      import java.util.List;
      
      global java.util.Set controlSet;
      global org.example.drools.service.DummyService dummyService;
      
      rule "will execute per each Measurement having ID color"
      no-loop
      when
       $m: Measurement( id == "color", $colorVal : val )
       String() from dummyService.dummy($m.getId(), $m.getVal())
      then
       controlSet.add($colorVal);
      end

       

      Compiling the generated model throws:
