[Dojo-interest] Whats wrong with this JSON Format?

I was thinking that you would want to set hierarchical to false. I stumbled
on this same topic when using the ItemFileReadStore. If hierarchial is true,
then all nested objects in your JSON will be treated as items. (In your
example, those 'manager' objects would become first-class 'items' in the
store). Often times, you only want the 'top-level' objects to be the items
in the store. This is what setting hierarchical to false will do.
In regards to caching, I'm not exactly sure what you mean. The
ItemFileRead/Write Stores are kind of a 'one and done' store where the
entire dataset is fetched and stored. Other stores allow for more finely
grained control of what data is fetched and when. Maybe you could provide a
little more insight and we could help you solve the caching problem.
