Antony Stubbs commented on LBCLASSIC-330:
-----------------------------------------

I'm sorry, I was asking for the line of code in the source code for logback that triggers the printout of the debug information, not the xml attribute that triggers it. As you can see I already have that.

> {code}
> If I remove the rolling file appender, debug output is shown.
> If I remove just the rollingPolicy, debug output is shown.
> If I remove just the <fileNamePattern>server-event.%i.log</fileNamePattern> the debug output is displayed and the exception about the missing field is shown.
> Seems related to http://jira.qos.ch/browse/LBCORE-38 and http://jira.qos.ch/browse/LBCLASSIC-62
