[OpenLayers-Users] getDataExtent() for GML layer?

[Robert Sanson]

I couldn't get getDataExtent()) to work for a OpenLayers.Layer.GML
 
I changed to a OpenLayers.Layer.Vector and then it worked:
 
var g =  new OpenLayers.Format.GML();
 
var fbndurl = "http://10.65.192.1/cgi-bin/agbwfs.exe?farmid="+farmid+"&request=getfeature&typename=farm&service=wfs&version=1.0.0&SRS=EPSG:2193&BBOX="+x1+","+y1+","+x2+","+y2+"&maxfeatures=120 ( 'http://10.65.192.1/cgi-bin/agbwfs.exe?farmid="+farmid+"&request=getfeature&typename=farm&service=wfs&version=1.0.0&SRS=EPSG:2193&BBOX="+x1+","+y1+","+x2+","+y2+"&maxfeatures=120' )";
OpenLayers.loadURL(fbndurl, '', this, fbndreturn);
 
function fbndreturn(fbndresponse) {
              fbnd = new OpenLayers.Layer.Vector("Farm boundary",
                  {isBaseLayer: false,
                   style: farm_style, 
                   extractAttributes: true }); 
              fbnd.addFeatures(g.read(fbndresponse.responseText));
              map.addLayer(fbnd);
              map.zoomToExtent(fbnd.getDataExtent());
}

The singleTile option is completely useless... as is the
extractAttributes option, I'm pretty sure...

Anyway, "yes, as of 2.7."
