[OpenLayers-Dev] Zoom Problems Switching Baselayers -- HELP!

[Gianni Barrotta]

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.
