Всего-то три часа заняло. Прогресс.
This method initializes layer.maxExtent, so 'zoom to layer' operations work properly. In latest open layers distro method getDataExtent() is not implemented for WFS and WMS layers. This method is a poor man's replacement. It's easy to generalize for WFS layers, if you like. I just needed to jury rig something fast.
var fixWMSLayerExtent = function(layer)
{
var readr = new Ext.data.XmlReader(
{ record: 'Layer'},
[
{name: 'name', mapping: 'Name'}
,{name: 'minx', mapping: 'LatLonBoundingBox > @minx'}
,{name: 'miny', mapping: 'LatLonBoundingBox > @miny'}
,{name: 'maxx', mapping: 'LatLonBoundingBox > @maxx'}
,{name: 'maxy', mapping: 'LatLonBoundingBox > @maxy'}
]);
var myStore = new Ext.data.Store({
url : "/MapProxy?url=" + layer.url +'&request=GetCapabilities' ,
reader : readr
});
myStore.load({'layer' : layer, callback: function(r, options, success)
{
var rindex = this.find('name', options.layer.name, 0, true, true);
var rec = this.getAt(rindex);
layer.maxExtent = new OpenLayers.Bounds(rec.data.minx, rec.data.miny, rec.data.maxx, rec.data.maxy);
} });
};
