Thank you all for your responses. It looks like we're setting the layout
within our code (although through a bit of a backchannel route). Not sure why
this does not appear under Turbine-2.3.1, but it does in 2.3.3. I've changed
our configuration table to use a different (pretty much empty) layout for the
JSON requests and it seems to be working.
Thanks again. ---
