[rules-users] How to Compute against WorkingMemory in Drools ?

[Wolfgang Laun]

>From the rule "CORRELATION" I can guess that
  class Alert {
     List<Alert> alerts = ...;
     public List<Alert> getAlerts(){ return alerts; }
  }
which is a little strange.

If you add the constraint alertDescription contains "ERR" to the
collect, you don't need the function checkForAlertDescription any
more.
