My apologies. For a Collection of objects, one must state which members of
the object in the list to include. For example, to retrieve every attribute
of the Product object:
products.*, productsTotal
...and one can select which attributes to include like so:
products.name, products.description, productsTotal
Credit goes to my colleague for figuring this out :) Hope this helps
others.
Cheers,
James
