-------------------------------------
Summary: Compilation fails when chaining methods with function calls as
params
Key: DROOLS-5641
URL: https://issues.redhat.com/browse/DROOLS-5641
Project: Drools
Issue Type: Bug
Components: executable model
Affects Versions: 7.43.0.Final
Reporter: Ciprian Chiru
Assignee: Luca Molteni
Given the following rule:
{code:java}
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{code}
The compilation fails with:
{code:java}

This error is reproducible with the latest _7.44.0-SNAPSHOT_ .
The parameters are flipped between the LambdaExtractor and the RuleMethods generated
classes.
