[opensocial] Re: Inconsistencies in obtaining and saving opensocial id's.
Keep in mind that most (all?) JavaScript implementations out there will choke if you try to store or manipulate 64-bit integers (signed or unsigned), so for all JS code, you should treat ids as strings. Of course, since ids are pretty much opaque values, this doesn't really cause any problems; for example, it would never be meaningful to add two user ids.

I haven't been paying attention, but I haven't heard something definitive about the id space. Anyhow. the Negative numbers might have something to do with unsigned long != two's complement signed long. So a 64bit id can be represented as an unsigned long (all positive numbers), or a two's complement signed long ( half of the bit space is negative ). I did bump into this earlier because they were giving out unsigned long ids, which java doesn't support, so we had to manually convert that unsigned long into a signed long.. hence we dealt with negative numbers.. :) On Nov 6, 2007 9:43 AM, Suhail Doshi <[EMAIL PROTECTED]> wrote: > > Sure I get an id like this: -751714324471179 > > > > On Nov 6, 10:20 am, "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> wrote: > > Hi, do you have any examples? > > > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "OpenSocial Developers" group.

Sure I get an id like this: -751714324471179 On Nov 6, 10:20 am, "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> wrote: > Hi, do you have any examples? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "OpenSocial Developers" group.
