Hi,

I'm a Perl novice and trying to learn Catalyst. In the application I'm building, I saved some objects from resultset inside one action and redirected to the other function, but it displayed a blank page with exception

Can't call method "class" on an undefined value at /usr/local/lib/perl5/site_perl/5.10.0/DBIx/Class/ResultSourceHandle.pm line 81, at /usr/local/lib/perl5/site_perl/5.10.0/DBIx/Class/Serialize/Storable.pm line 14, at /usr/local/lib/perl5/site_perl/5.10.0/Object/Signature.pm line 19 Example of the codes: 
sub foo {
   ...
   @some_records = $c->model("DB")->resultset("MyTable")->all;
   $c->session->{data} = \@some_records;
   ...
   $c->redirect->($c->uri_for('do_something'));
}

sub do_something {
    $c->stash->{template} = 'do_something.tt2';
}

In do_something.tt2:
[% FOREACH record IN c.session.data %]
[% record.comment_field %]
[% END %]
etc.

I did some web search and saw some responses that it's because the database connection was reset/lost during redirect, and it was suggested to use DBIx::Class::Schema freeze/thaw so solve the problem. But I have trouble understand the exact syntax to use freeze/thaw in the above codes. Thanks.
