Accept: application/x-page-fragments;views="subscribers=+subscriber-
portlets,
count=+subscribers-count"
That should return a JSON dictionary containing two keys: subscribers
containing the result of the +subscriber-porlets view and count
containing the
result of the +subscribers-count view.
That removes the wiring that has to be done now server side to map
these
existing views to the HTML representation of fields, removes the
problematic
limitation of having only HTML representation and allows us to
retrieve
efficiently all the fragments we need on the page.
