Re: [xwiki-devs] Xwiki 2.0 migration problems

Shift-reload pages, every time you upgrade Javascript on an Xwiki- based site. Especially, before saving any documents, administration, users, preferences, etc, be sure to shift-reload otherwise you'll have problems when a new Xwiki meets the old Javascript stored in the browser- cached from the previous installation. It would be a great "defensive programming" improvement for Xwiki to check the browser-cached javascript, e.g. by expected version#, or even better, by "digital signature" , before proceeding, in order to prevent this potential class of problems.
