At this point, $order ISA Handel::Iterator.

Now, as the message states, we're trying to call the 
Handel::Iterator::items method, which doesn't exist.

Instead, change the first part to get the first order found:

      my $order = Handel::Order->load({
         id => $c->stash->{'orderid'}
          }, RETURNAS_ITERATOR
      )->first;


Now, $order ISA Handel::Order, and $order->items will do what you want.


Now with that said, I'll claim responsibility for these sorts of 
problems. Early on, I tried to make too load()/items() smart about what 
they returned.

If there was one item, I'd return an item instance instead of an 
interator. The same goes when loading carts or orders. Sometimes, that 
behaviour sucked, so I tossed in the RETURN_AS constants to let users 
specify what they really want (and to fix some obscure things under TT 
wnar wantarray). Things are no way too complicated.

At some point in the future, I plan on ditching all of the mess in 
favour of always returning a Handel::Iterator. Since that will be a big 
breaking API change, I'll save it for 1.0.

On a more positive note, thanks for using Handel! :-)
