[OpenLayers-Users] Problem with polar projection on Antartica

[springrider]

Thanks Jon for your reply

Sorry I was not really explicit about the result i had.

This is the request which is sent to my Geoserver:
GET /geoserver/wms?service=wms&LAYERS=fifao:CONTINEENT_GAUL
&SRS=EPSG:3031&VERSION=1.1.1&REQUEST=GetMap&STYLES=
&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fjpeg
&BBOX=-12399999.999999989,8762666.666666664,8762666.66666668,29925333.333333332
&WIDTH=256&HEIGHT=256

So the SRS to be used is correct (3031) but what is sent for the bounding
box seems to be wrong in respect to what i have specified...

As you were suggesting in one of your previous post, could it be related to
ZoomToMaxExtent?

I tried to add the projection also for the baselayer but with no results:
	var basemap = new OpenLayers.Layer.WMS( "test",
				"http://193.43.36.238:8484/geoserver/wms?version=1.1.1",
				{layers: 'fifao:CONTINEENT_GAUL',
                                 srs: 'EPSG:3031'});
	basemap.addOptions({isBaseLayer: true});

Thanks for your help and for telling me if the options and the way i used
them are corrects.

Cheers

Sylvain
