Subject: make_immutable breaks methods using _call_kernel_from_my_session
Download (untitled) / with headers
text/plain 834b
When __PACKAGE__->meta->make_immutable; is called from a module using MooseX::POE (as is recommended by Moose Best Practices), the "new" method provided by MooseX::POE::Meta::Trait::Object to replace the default Moose-provided constructor will not be executed any longer. It seems that MooseX::POE::Meta::Trait::Constructor partially implements the behavior needed for MooseX::POE to function after make_immutable. A functional POE session is created and START methods are called as expected. However, this method of POE session creation does not register a hook for _call_kernel_from_my_session, which turns all the various helper methods defined by MooseX::POE::Meta::Trait::Object into no-ops. I have attached a test case which should say "test" every second. It exits immediately. If make_immutable is commented out, it works.
{ package mxp; use MooseX::POE; sub START { $_[0]->delay('test', 1); } event 'test' => sub { print STDERR "test\n"; $_[0]->delay('test', 1); }; __PACKAGE__->meta->make_immutable; }; { package main; use POE; my $mxp = mxp->new; POE::Kernel->run; }; 1;

What about this patch? This registers _child, _parent and _call_kernel_from_my_session if the MooseX::POE instance is constructed by the constructor built in MooseX::POE::Meta::Trait::Constructor.
