[rules-users] Drools 5.5.0.Final : Rule Trigger Issue

[Wolfgang Laun]

Rule 1:
This could result from not updating the WorkflowProcessInstance after
creating the Variable "piRequest". Hard to tell without seeing all of
the code...

Rule 2:
Simply incorrect syntax. Either use
   $r: Request( ADV == "N" )
or
   $r: Request()
   eval( $r.getADV().equals( "N" ) )

Make sure to use Java code inside eval.
