Hi Dan,
I was trying to poke through some of the server code and I was struggling to
fall the flow of the code (lots of hidden magic with turbogears and
cherrypy). Of course, with the turbogears->flask and cherrypy->flask
wrappers, it makes things more challenging. :-)
So I thought if I start peeling away some of the cherrypy stuff it would
help me understand some of the code better. Using a lot of ignorance, I
pulled out this patch inside beaker-in-a-box:

Restarting the httpd service and trying to export a CSV led to a 500
failure, with the beaker debug logs spitting out 'cherrypy can not iterate
through the response' failures. Not surprised.
I am sure I am untangling spaghetti here, but I guess I was hoping I would
eventually hit one of your cherrypy->flask wrappers.
Is there a good direction to go here or am I in for a long ride of
unhappiness?
Also for some reason when I am in IntegrationTests and run ./run-tests.sh, I
get the following error:
