Re^2: Scratchpad (Edit)/Personal Nodelet (add to scratchpad) : Lost update problem

[ysth]

I'd lean toward just bailing out with a "Warning! Scratchpad has changed since editing began; return to display view or Submit again to override" if the update detects that the scratchpad was changed from how it was when the edit page was generated. Two ways to detect this: checksum or hidden field with the original content; which is better?
