[OpenLayers-Users] A WMS layer as base layer

[Andrés Maneiro]

Hello,

I've configured my map to use 3 different base layers (open street map, 
google map & google hybrid) with success. Nevertheless, I'm struggling 
to get as base layer a plain WMS. The symptons are:

   - when the user changes the base layer, the boundingbox gets zoomed 
in (which no happens when I change between OSM and google for example).

  - when the user changes the base layer, it is displaced someway to the 
north, so the features have no rendered in the proper place.

I guess it has something to do with the resolutions and scales, as 
discussed here: http://trac.osgeo.org/openlayers/wiki/SettingZoomLevels

But I've tried several alternatives with no success. Just in case 
someone has the time to review it, here the WMS I'm trying to set as 
base layer:

Some ideas/suggestions?

best,
amaneiro
