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:
