Well, how could it not work? I changed my config to:
<evaluator name="CALLER_EVAL" class="ch.qos.logback.classic.boolex.OnMarkerEvaluator">	<marker>MY_MARKER</marker></evaluator>...<pattern>... %n%xThrowable{full, CALLER_EVAL}%caller{5, CALLER_EVAL}</pattern>
Just what I need. Sorry about this RTFM.
Thanks, ceki.
