Hi,

I am working on a system where I need to correlate few error conditions happening in the network infrastructure. I have gone through the documentation for Jboss rules engine (Drools) and I am planning to use it for the correlation purpose.

Can anyone let me know a way in which I can get an object from workingmemory in the "then" part of the rule? For e.g., I need the following

rule "new error"
        when
                $error : Error (state == NEW_ERROR)
        then
                (search workingmemory if this error was already registered)
                if (found)
                {
                        $errFromWorkingMemory.setLastTimestamp(currentTimestamp)
                        retract($error);
                }
End

Thanks,
Ashfaq
