is {wrapAround180:true} compatable with 9.3.1 hosted map services?

Discussion created by mschmoll on Mar 31, 2011
We're testing version 2.2 of the JS API internally with cached map services hosted on AGS 9.3.1.

The wrapping is happening (cool!), but the tiles around the dateline are getting dropped (i.e. there's a white vertical gap). 

Is there a compatibility problem between JS API 2.2 and map services hosted on 9.3.1, or is something else going on?
