wrapAround180 does not work well with esri.geometry.Extent

[mikewebster]

I believe all the geometries work well with rendering when panning across the dateline, except for the extent geometry. I attached a snapshot of what I see.

You can also take the example @

and apply

wrapAround180:true

to the esri.Map construct

Just a thought . . . a temp and easy solution incase you need your extent to wrap might be to convert it to a polygon.
