I have the following:

{
  package MyApp;
  use Moose;
  use Moose::Util qw( apply_all_roles );
  with 'MooseX::Log::Log4perl';

  sub BUILD {
    my $s = shift;
    # apply_all_roles($s, 'BarCollector');  # if you uncomment this li
+ne, logging doesn't work anymore
  }
  sub print_something {
    my $self = shift;
    $self->log->info('This does not print when apply_all_roles is used
+.');
  }

}

{
  package BarCollector;
  use Moose::Role

  # does nothing 
}

#! /usr/bin/env perl

use File::HomeDir;
use Log::Log4perl;
BEGIN { Log::Log4perl->init_once(File::HomeDir->my_home . '/test.cfg')
+ };
use MyApp;


my $app = MyApp->new();

$app->print_something;

__END__
# test.cfg config file:
log4perl.logger.MyApp=TRACE, LOG

log4perl.appender.LOG=Log::Log4perl::Appender::ScreenColoredLevels

log4perl.appender.LOG.layout=PatternLayout
log4perl.appender.LOG.layout.ConversionPattern=%c - %m%n

As noted in the comment, when the line that contains apply_all_roles is uncommented, log messages no longer work. There are no errors.

Update: One other clue is that when I change the first line of the config file to: log4perl.rootLogger=TRACE, LOG

I get output, though the category looks something like this: Moose.Meta.Class.__ANON__.SERIAL.1

Any workaround to this?

Update 2: Possible workaround?

I discovered if I slap $s->log->trace('print this'); before the apply_all_roles method is called, everything works as expected. Is there a better way?
