Leo and Peter, thanks for the answers!

Peter,

Thanks for the suggestion, quite simple and quick.
I ended up copying and modifying Excalibur Logger's FormatFactory
so has to have the "extended" type as well as my custom one.
All of this works great!

Thanks again,
Shash

Hi there,

Unfortunately there is no inbuilt way to fix this at this stage. However for
an imediate fix to your problem you can write your own pattern formatter
(copy paste from ExtendedPatternFormatter if you want). Then replace
"getMethod" with changes as below (look for //PD: to see changes).

    /**
     * Utility method to format category.
     *
     * @param event the event
     * @param format ancilliary format parameter - allowed to be null
     * @return the formatted string
     */
    private String getMethod( final LogEvent event, final String format )
    {
        final ContextMap map = event.getContextMap();
        if( null != map )
        {
            final Object object = map.get( "method" );
            if( null != object )
            {
                return object.toString();
            }
        }

        //PD: Changed the next line to refer to Framework Logger class
instead
        final String result =
              StackIntrospector.getCallerMethod( LogKitLogger.class );
        if( null == result )
        {
            return "UnknownMethod";
        }
        return result;
    }
