Attempting to clear the view.html/config.html tile cache - so far the only way I've found is to actually restart the Jive webapp.
Originally I looked under /admin/settings-cache!input.jspa and flushed everything - this does not seem to flush the cache though.
It looks like Jive stores a copy of the information in /usr/local/jive/var/work/sbs/httpResponses.data - but clearing/deleting this file does not seem to affect what is served.
The actual request seems to be going to /gadgets/ifr?url= which has a &nocache=0 parameter on the end. Setting this parameter to &nocache=1 yields the updated content when opening the link in a new window, however, it does not seem to "load" the fresh copy into the cache that's served by the page.
Again - I'm probably missing something very, very obvious in the docs...
Pinging Ryan Rutan to see if he has any insight.
