Edson 2007/8/30, Tim.Nguyen(a)expeditors.com <Tim.Nguyen(a)expeditors.com&gt;: Hi group, Currently I have to use eval to access to lower lever of an attribute. For example: rule "test rule" when $person: Person () eval (($person.getContact() != null) && ($person.getContact().getEmail() == null)) then System.out.println ("Email address is missing") end Is there anyway not to use eval. I would like to do something like this: $person: Person ($contact: contact != null, $contact.getEmail() == null) but it throws errors Thanks, Tim _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- Edson Tirelli Software Engineer - JBoss Rules Core Developer Office: +55 11 3529-6000 Mobile: +55 11 9287-5646 JBoss, a division of Red Hat @ www.jboss.com _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
