memberOf and not memberOf not working
-------------------------------------

                 Key: JBRULES-953
                 URL: http://jira.jboss.com/jira/browse/JBRULES-953
             Project: JBoss Rules
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Drl Parser/Builder
    Affects Versions:  4.0.0.MR3
         Environment: Windows XP, Drools MR3
            Reporter: Brian Enderle
         Assigned To: Mark Proctor


The use of "memberOf" and "not memberOf" does not appear to do anything as it always evaluates to true.

Example:

given an Address object with countryCd of "US" & List of country codes of {"US", "MX" and "CA"}

rule "Country must be US, MX or CA"
   when
      $i : Address( countryCd != null, countryCd not memberOf countryCodes, $countryCd : countryCd )
   then
      System.out.println("- Country must be US, MX or CA");
end

rule "Country must not be US, MX or CA"
   when
      $i : Address( countryCd != null, countryCd memberOf countryCodes, $countryCd : countryCd )
   then
      System.out.println("- Country must not be US, MX or CA");
end

The results of these two rules is the following:
- Country must be US, MX or CA
- Country must not be US, MX or CA

One of these should not fire, in this case the first rule should not evaluate to true and therefore should not fire.
