[Catalyst] Moose attributes not initializing when including FormHandler form

I don't know if this is a Moose, FormHandler or Catalyst problem, so I'm
starting here, hope that's OK!  I have an existing App that I'm just
starting to convert over to using FormHandler from FormFu, and so far I've
only done that for one controller's forms, others still employ FormFu.

Here's the top of the controller which has switched...

package WsdSis::Controller::LearningPlan;
use Moose;
use namespace::autoclean;
use 5.010;

BEGIN {extends 'Catalyst::Controller' }
use WsdSis::Form::LearningPlan::Start;

Now I have another controller that builds some per context Moose objects to
create categories/reports and when I hit those now (not touching
WsdSis::Controller::LearningPlan except on startup) I'm getting

Caught exception in WsdSis::Controller::Reports->data "Can't use an
undefined value as a HASH reference at
/srv/WsdSis/script/../lib/WsdSis/Model/Categories/CategoryList.pm line 88."

referring to

88: $self->_temp_details->{$category} =3D {
89:     type_id =3D> $datatype_id,
90: };

and yet defined at the top of  WsdSis::Model::Categories::CategoryList is

package WsdSis::Model::Categories::CategoryList;
use Moose;
use Moose::Util::TypeConstraints;
with qw( MooseX::Traits WsdSis::Model::Categories::Roles::GetData );
use Data::Dumper;
use namespace::autoclean;

has 'ctx' =3D> (
    is       =3D> 'rw',
    required =3D> 1,

has 'list' =3D> (
    is       =3D> 'ro',
    required =3D> 1,
    isa      =3D> 'ArrayRef',

has 'student_data_store' =3D> (
    is  =3D> 'ro',
    isa =3D> 'HashRef',

has details =3D> (
    is      =3D> 'rw',
    isa     =3D> 'HashRef',
    builder =3D> '_build_details',

has _temp_details =3D> (
    is      =3D> 'rw',
    isa     =3D> 'HashRef',
    default =3D> sub{ {} },

So _temp_details has a default which is first called upon
in _build_details.  All this works fine if I comment out the

use WsdSis::Form::LearningPlan::Start;

in WsdSis::Controller::LearningPlan!!

What am I doing wrong?  Why isn't $self->_temp_details being initialized
when I use an HTML::FormHandler form package in a different controller?
