[Catalyst] DBIx::Class/TT Pager Question

[Dennis Daupert]

I'm having a bit of a go of getting all the bits in place to do paging. The error I'm hung on is:
"Can't call method "pager" on unblessed reference"

Here's the story:
My display template first asks the user to select a gallery to display, then displays a list of thumbnail images. My controller 1) runs query to get the galleries for the display template; 2) writes an HTML::Widget form; 3) checks to see if there is a $selected_gallery; 4) If there is, query db for photos. 

Line below marked # ??? gives the error; removing that line, I can select a gallery and display the images -- but without paging.

# - - - - - - - - - - - - - - - - - - 
package Catapult::Controller::Photo::Gallery;
# - - - - - - - - - - - - - - - - - - 
use Data::Page;

################
sub display : Local {
  my ($self, $c) = @_;

  $c->log->debug("Get Galleries ");
  my @galObjs = $c->model("CatapultDB::Galleries")->all();
  my @gals = map {$_->id => $_->name }
                sort {$a->name cmp $b->name} @galObjs;
  my $selected_gallery = $c->request->params->{select_gal};

<snip>
make the html::widget form here
<snip>

if ( $selected_gallery ) {

  my $pager = Data::Page->new(); 

  $c->log->debug("Selected Gallery: $selected_gallery");
    $c->stash->{photos} = [$c->model('CatapultDB::Photos')->search(
      {
        'gallery.id' => $selected_gallery
      },
      {
        join     => [qw/ gallery /],
        prefetch => [qw/ gallery /],
        rows => 1,
      }
    )];

$c->stash->{pager} => $c->stash->{photos}->pager(); # ???

  }
# - - - - - - - - - - - - - - - - - - 
display.tt
# - - - - - - - - - - - - - - - - - - 
[% IF photos.size %]

<h3>Gallery: [% photos.gallery.name %]</h3>

<div id="thumbnails">

       title="[% photo.name %]">

       alt="[% photo.gallery.name %][% photo.gallery.name %]"></a>
 </li>
[% END -%]
</ul>
</div>

    [% IF pager.previous_page %]
    <a href="[% c.request.uri_with( page => pager.previous_page ) %]">Previous Page</a>
    [% END %]
    [% IF pager.next_page %]
    <a href="[% c.request.uri_with( page => pager.next_page ) %]">Next Page</a>
    [% END %]

[% ELSE %]
    <h3>There are currently no photos in this gallery.</h3>
[% END %]
# - - - - - - - - - - - - - - - - - - 

Help is much appreciated.
