[jboss-jira] [JBoss JIRA] (DROOLS-5549) Drools model compilation fails when using object builders within method calls

[Ciprian Chiru (Jira)]

     [ https://issues.redhat.com/browse/DROOLS-5549?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ciprian Chiru updated DROOLS-5549:
----------------------------------
    Description: 
Given the example rule below:
{code:java}
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))
then
 controlSet.add($colorVal);
end{code}
 

compiling the rule with kie-maven-plugin, it throws the error:
{code:java}
...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{code}
 

Same rule when not pre-compiled returns the error:
{code:java}
[org.example.drools.service.RulesSession] (main) Message [id=1, kieBase=defaultKieBase, level=ERROR, path=/home/vagrant/git/drools-rules-engine-prototypes/drools-kjar-project/rules/target/classes/rules/dummy-rule.drl, line=-1, column=0
 text=Unable to Analyse Expression dummyFunction(Map.of($colorVal)):
[Error: unable to resolve method using strict-mode: java.util.Map.of(java.lang.String)]
[Near : {... dummyFunction(Map.of($colorVal)) ....}] {code}
 

 

  was:
Given the example rule below:
{code:java}
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 )
 $val: String() from dummyFunction(Map.entry($colorVal))
then
 controlSet.add($colorVal);
end{code}
 

compiling the rule with kie-maven-plugin, it throws the error:
{code:java}
...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{code}
 

Same code works fine if the rules are not pre-compiled.
