             Summary: Parser and Canonical Model Compiler error on Conditional Named Consequence
                 Key: DROOLS-4684
                 URL: https://issues.jboss.org/browse/DROOLS-4684
             Project: Drools
          Issue Type: Bug
          Components: core engine
    Affects Versions: 7.28.0.Final
         Environment: macOS 10.14.6, OpenJDK 1.8.0_222
            Reporter: Duncan Doyle
            Assignee: Mario Fusco


See reproducer here: https://github.com/DuncanDoyle/drools-conditional-named-consequence-issue

When you use a Conditional Named Consequence {code}if{code} definition directly after an {code}accumulate{code}, Drools gives the following error when parsing the DRL:

{code}
[ERROR] Failed to execute goal org.kie:kie-maven-plugin:7.28.0.Final:build (default-build) on project drools-conditional-named-consequence-issue: Execution default-build of goal org.kie:kie-maven-plugin:7.28.0.Final:build failed: Unable to get KieModule, Errors Existed: Error Messages:
[ERROR] Message [id=1, kieBase=defaultKieBase, level=ERROR, path=rules.drl, line=19, column=0
[ERROR]    text=Unable to resolve ObjectType 'if']
[ERROR] ---
[ERROR] Warning Messages:
[ERROR] ---
[ERROR] Info Messages:
[ERROR]
{code}

When you add a constraint between the {code}accumulate{code} and the {code}if{code} statement of the Conditional Named Consequence, it works fine.

Also when you try to generate the canonical model from a DRL that contains a Conditional Named Consequence, you get the following error:
{code}
[ERROR] Failed to execute goal org.kie:kie-maven-plugin:7.28.0.Final:generateModel (default-generateModel) on project drools-conditional-named-consequence-issue: A type incompatibility occurred while executing org.kie:kie-maven-plugin:7.28.0.Final:generateModel: org.drools.compiler.lang.descr.NamedConsequenceDescr cannot be cast to org.drools.compiler.lang.descr.PatternDescr
