Hello, I am a newbie to drools and I have a question on the 'drools' global (?) variable. rule "035" when MessageBodyType($l : lineItems) eval(! dao.checkParty($l, "BY", drools)) then appendMessage(drools) end In the above rule, when the checkParty method is called, I am getting a null value for drools variable. Whereas when the append message is called I am getting a "DefaultKnowldgeHelper" object for drools variable. Can I use 'drools' variable in the when part ? Thanks for your help. -- View this message in context: http://drools.46999.n3.nabble.com/drools-variable-tp3586514p3586514.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
