Thanks Felix. That worked. I’ve now included the script, plus my options
script, the theme css and language css in the TMLs that need it, and Offline is
now working well.
BTW, I think Offline.js has a flaw in its init logic which could still occur
sometimes. It assumes that if document.readyState is not “complete” then
document event “DOMContentLoaded” must not yet have happened, which is a wrong
assumption that leads to “init” not being called and therefore the UI not being
set up.
By comparison, Tapestry’s jquery.js module is smarter - it listens for document
event "DOMContentLoaded” and, just in case that has already happened, for
window event “load”. On either of those events it removes both listeners.
