in reply to Use Moose in Controller and Model

I think the problems you are experiencing stem from not inheriting from Moose::Object. You can warn out the values in @ISA for the three different samples to verify.

From the Moose documentation:

extends (@superclasses)

This function will set the superclass(es) for the current class.

This approach is recommended instead of use base, because use base actually pushes onto the class's @ISA, whereas extends will replace it. This is important to ensure that classes which do not have superclasses still properly inherit from Moose::Object.

    Thanks. This is a test I did. I am not sure if I am right or wrong but I guess in the second case the superclass of Item becomes Moose::Object, not Catalyst::Controller::FormBuilder, and that's why Catalyst is complaining about. Am I right? 
    [1]
use Moose;
BEGIN { extends 'Catalyst::Model::DBIC::Schema' };
print "$_\n", foreach @MyApp::Controller::Item::ISA;
<result>
Catalyst::Controller::FormBuilder
[2]
use Moose;
use base qw/Catalyst::Controller::FormBuilder/;
print "$_\n", foreach @MyApp::Controller::Item::ISA;
<result>
Moose::Object
Catalyst::Controller::FormBuilder
