<br>Hi all, <br><br>When exceptions occur during runtime of drools, is there a list of things to see to understand what may be causing <br>this to happen ? I know it is a very generic question. I want to see if there is a methodical way to understand what
<br>to look for ?. <br><br>org.drools.RuntimeDroolsException: Exception executing predicate com.makesys.fs.is.dnpiac.vendorBehaviour.snmp.Rule_Cisco_Systems_0ReturnValue0Invoker@39d31fda<br>INFO | jvm 1 | 2007/09/14 16:46:33 | at
