Re: Example implementation for user prefs?
Dan,
Have you seen an timing issues with this setpref implementation? I am
seeing strange things. I'm using the horoscope gadget which renders
differently if the user preferences have been set (it shows your horoscope
based on a uid). Sometimes this works and sometimes it doesn't. What's
strange is it seems that switching the id of the html element (which then is
used as the siteid) is what's causing the behavior to change. I'll do some
more investigation, just wondered if you had seen any peculiarities like
that.
