[OpenLayers-Dev] Patrch for getting vector drawing working over the 180 line going.

[Andreas Hocevar]

Hi,

to save you efforts in persuing your original attempt to modify the sketch handlers, I have created http://trac.openlayers.org/ticket/2787 with a patch.

This does not solve all vector layer and date line issues though. If you play with the spherical-mercator example after applying my patch, you will see that features crossing the date line can turn invisible when zoomed out and the map extent changes.

Regards,
Andreas.

So if you store a feature with coordinates like -181 0, -179 0, GeoServer will accept that by default (but not in cite testing mode). And it will also return coordinates like this as stored, i.e. not as 179 0, -179 0.
