Parenthesis required for 'exist' rule in Split constraint editor
----------------------------------------------------------------

                 Key: JBRULES-1791
                 URL: https://jira.jboss.org/jira/browse/JBRULES-1791
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Rule Flow
    Affects Versions: 4.0.7
         Environment: Fedora 5, tomcat 6, drools 4.0.7
            Reporter: Roger Lefebvre
            Assignee: Mark Proctor
            Priority: Minor

A rule such as:

        exists Item()

throws InvalidRulePackage "Unexpected token exists ..." when doing performing ruleBase.addPackage(builder.getPackage()).
Adding parenthesis resolves the problem.
e.g.

        exists (Item())

Similar applies to not and other qualifiers/functions.
