Subject: Question about Lo4R

Hello,
    I'm having an issue with a Formatter for Log4R.

I'm trying to use the %c format directive to display the Line Number of
the file and for some reason it keeps throwing an error.

I'm using Ubuntu Breezy 5.1, Ruby 1.8.3, and Log4R 1.0.5. Is anyone else
having any similar issues?

Error Msg :
(eval):2:in `format': undefined method `[]' for nil:NilClass (NoMethodError)
        from
/usr/local/lib/site_ruby/1.8/log4r/outputter/outputter.rb:118:in `format'

Here is the small snipbit of code

require 'log4r'
include Log4r

class MyClass


        def initialize
                puts('init')
                @my_log = Logger.new 'myLog'
                formatter =
                        PatternFormatter.new(
#:pattern => "%l[%d] %t %1M")
:pattern => "%5l [%d] %t: %.25M",
:date_pattern => "%H:%M:%S")
                @my_log.outputters = FileOutputter.new('myLog',
:filename => "log_file",
:trunc => false,
:formatter => formatter)

                puts(Kernel.caller[0].to_s)
        end

        protected
        def logger
                puts("got logger")
                @my_log
        end

end

class MyChild < MyClass
        def initialize
                super
        end

        def happy
                logger.debug('happy')
        end
end

c = MyChild.new
c.happy


I'd appreciate any and all input. Thanks!
