[rules-users] Log messages are in not in the expected order

Hi All, Im writing an event driven application where I need to log 1. When a particular event get triggered. 2. When a particular event pattern (condition) is matched. Events are fired both in the Java code as well as within the drools rule RHS. Event patterns are matched in the drools LHS. Th

This is impossible to have in a Rete based RBS, because identical LHS patterns typically result in a single node in the network. Hence, there is, in general, no generic way of obtaining anything related to "source code location" for any LHS expression. -W On Sat, Feb 20, 2010 at 8:11 AM, Malinda K

Many thank Pavel. But I dont think I followed RuleXor in your reply. But I tried to insert an event with a key value in the RHS. The same value I used in LHS with other business logic to avoid repeated execution. e.g. when not EventR(Id="KEY") //Other logic then //Other executions in
