Hi Bill,

I suspect this is the "culprit".

# Version 2.14a - 2nd February 2006               ## DEVELOPER RELEASE ##
#------------------------------------------------------------------------

* Activated a patch in Template::Stash from Stephen Howard which adds
   code for the full set of fallbacks for dot ops called against
   objects which don't implement the specific method.  For example
   [% hashobj.vmethod %] [% listobj.2 %] and [% listobj.vmethod %] now
   all work with the Perl Template::Stash.  Added code to the XS Stash
   to do the same and updated tests.

TT is now calling the hash.size virtual method, whereas in 2.14 and earlier
it couldn't find the hash.size virtual method so automagically upgraded the
single record to a list and called the list.size vmethod instead.

In this case you can put a .list on the end of cart.items to explicitly
upgrade a single item to a list:

   items = cart.items.list
