             Project: JBoss Rules
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Drl Parser/Builder
    Affects Versions: 3.0.4

            Priority: Minor


[Maybe assign to Edson, he asked me to open in mailing list thread "Yet another or question"]

On the 3.0.x branch (update from this time) when declaring this rule:

query "multipleMatchesPerTeamPerDay"
    $team : Team();
    Match( $id : id, homeTeam == $team, $day : day )
        || Match( $id : id, awayTeam == $team, $day : day );
    exists Match( id > $id, homeTeam == $team, day == $day )
        || exists Match(id > $id, awayTeam == $team, day == $day );
end

It reports an error:
  org.drools.rule.InvalidRulePackage: Duplicate declaration for variable '$day' in the rule 'multipleMatchesPerTeamPerDay'


Testcase patch coming up.
