[rules-users] Nullpointer inserting fact.

[Edson Tirelli]

   Improve your rule constraints:

rule "..."
ruleflow-group "invoke"
salience 10
when
       $web : WebService ( invoke == null )
then
      Invoke inv = new invoke();
      $web.setInvoke(inv);
      update( $web );
      insert(inv);
end
