This is an MVEL problem that Mike fixed in one of the latest versions:
it was raising that error message when unable to resolve a variable reference
(processor in this case).<br>
<br>
Can you please confirm what versions of drools and mvel are you
using?<br>
<br>
Also, try to use mvel syntax, just in case:<br>

What is Processor? Doesn't look like it is a bound variable. Is it from
DBSubscription? <br>
