Subject Re: JSON plugin 0.33 and Struts 2.1.6 (integrated with Spring 2.5)
Date Fri, 28 Aug 2009 12:41:59 GMT

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
