    Description

      Given the example rule below:

      import org.example.drools.model.*;
import java.util.Map;
global java.util.Set controlSet;


function String dummyFunction(Map m) {
 return "test";
}

rule "will execute per each Measurement having ID color"
no-loop
when
 Measurement( id == "color", $colorVal : val )
 $val: String() from dummyFunction(Map.of($colorVal, "something"))))
then
 controlSet.add($colorVal);
end

       

      compiling the rule with kie-maven-plugin, it throws the error:

      ...target/generated-sources/drools-model-compiler/main/java/rules/Rules57a04348fad44377b9eacd9bb5741999RuleMethods0.java:[30,117] cannot find symbol
[ERROR] symbol: variable $colorVal
[ERROR] location: class rules.Rules57a04348fad44377b9eacd9bb5741999RuleMethods0

       

      Same rule when not pre-compiled runs fine.

          is duplicated by

          Bug - A problem that impairs or prevents the functions of the product. DROOLS-5548 Model compiler cannot generate declaration from a function call

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
