Re: [logback-user] Filtering "unknown" mdc discriminator events

      The <OnMismatch> and <OnMatch> elements should be embedded in the 
<filter> element, and not the <evaluator> element.

Hi,
This has been written about before in this list, and I thought it would
be easy, but I'm getting nowhere. Can anyone suggest what I'm doing
wrong? I can confirm that my filter code is running (I see the print
statements) but no matter what I return, I still end up with a log like
"unknown/batchqc-<timestamp>" containing plenty of log data.
I would like to eliminate these logs completely, and write logs using
this sifter only when articlePath is set.
The status listener is reporting:
12:03:35,652 |-ERROR in ch.qos.logback.core.joran.spi.Interpreter@25:37
- no applicable action for [OnMismatch], current pattern is
[[configuration][appender][filter][evaluator][OnMismatch]]
12:03:35,652 |-ERROR in ch.qos.logback.core.joran.spi.Interpreter@26:34
- no applicable action for [OnMatch], current pattern is
[[configuration][appender][filter][evaluator][OnMatch]]
What am I missing?
