Hi,
IIRC OpenLayers does not read the boundedBy of the whole
FeatureCollection, only of individual features. I've added my own custom
patch but it's only for GML v3, maybe you can do something similar for
GML.v2.

Hello,
I'm trying to get the boundedBy of a whole feature collection (in this
example
there is only on feature).
I follow this exemple http://trac.openlayers.org/ticket/1613
var g = new OpenLayers.Format.GML.v2(options);
var features = g.read(response.responseXML || response.responseText);
// boundedBy will contain the boundary of the whole feature collection
// easy for zooming to the selection / collection
console.log(g.boundedBy);
The result in my log is: undefined
here is my script:
script type=text/javascript
function parseData(req) {
var format = new OpenLayers.Format.GML.v2({
featureType: states,
featureNS: http://www.openplans.org/topp;,
geometryName: the_geom,
xy: false
});
var features = format.read(req.responseXML || req.responseText);
console.log(features.boundedBy);
}
function load() {
OpenLayers.loadURL(owls1.xml, , null, parseData);
}
/script
The beginning of my owls1.xml:
