I had a similar problem and solved it by passing the maxExtent to options of
my layers and setting the tileOrigin before switching the layer.
It's quite weird, I suppose the problem is that you don't call this method:
/** When the layer is added to a map, then we can fetch our origin
* (if we don't have one.)
*
* @param {OpenLayers.Map} map
*/
setMap: function(map) {
OpenLayers.Layer.Grid.prototype.setMap.apply(this, arguments);
if (!this.tileOrigin) {
this.tileOrigin = new OpenLayers.LonLat(this.map.maxExtent.left,
this.map.maxExtent.bottom);
}
},
when you switch the layer, and so the tile origin is not updated...but I
don't know if this could be the right fix.
