Hi Yong
How are you going to get them from the client (I take it you mean browser) into
the Userprefs object in the gadget?
I think you may find you can get them straight into the UserPrefs object by
doing something in GadgetFactory. It seems to me that this class is used by
both the gadget rendering call and the metadata call so doing it here will mean
that they end up on both the metadata (both on the iframeUrl field in the
metadata and the UserPrefs object) and in the gadget. It looks like they are
injected into the gadget by inserting a line like this:
gadgets.Prefs.setDefaultPrefs_({"name":"freddy","coke_pepsi":"coke","followup":"yes","fav_foods":"","diet":""});
at the end of all the other Javascript injection.
Anyway I'd be interested to know how you solve it.
Did you solve the first problem about gadgets.io.makeNonProxiedRequest and a
callback?
We're just using Ajax (were on the same domain) to make the call to save the
prefs.
Cheers
Justin
