Hi Mauricio,,

I have already declared it as an event....  as shown below... yet it
cribs....


declare EligibleAlert
    @role( event )
//    @expires(90s)
end



rule "Check if EligibleAlert is an Signature Event"
agenda-group "enrichment"
auto-focus true
//salience 100
no-loop true
when
    $list : EventSignatureList();
    $p : EligibleAlert($a : alert, $a.eventSignatureProcessingStatus!="TRUE"
);

    eval((ifMatchesSyslog($list.getAllSyslogMnemonics(), $a)!=null)  )
then
        try{
                WorkingMemoryEntryPoint eventsignaturestream =
drools.getEntryPoint("EVENT SIGNATURE STREAM") ;
                eventsignaturestream.insert($p);
                } catch(Exception e)
        {
            log.error("[EventSignatureRules] - exception in Check if
EligibleAlert is an Signature Event alert[ids=" + $p.getAlert().getId() +
"][error:" + e.toString() + "]");
        }
end
