[OpenLayers-Users] Highlight on hover

[Steve.Toutant at inspq.qc.ca]

I got this in the response <gml:Box srsName="EPSG:900913">
which is the same as the map projection.

I forgot to say that even if the feature is added to the vector layer I 
get this message in line 724 of OpenLayers.js
xmldom.loadXML(text);return xmldom;}),this),function(){return new 
DOMParser().parseFromString(text,'text/xml');},function(){var req=new 
XMLHttpRequest();req.open("GET","data:"+"text/xml"+";charset=utf-8,"+encodeURIComponent(text),false);if(req.overrideMimeType){req.overrideMimeType("text/xml");} 


I click on Continue button and then the features are added.

Hi Steve.

A potential reason is that the GML you're receiving does not use the
same SRS as the one of your map.
You may check this using FireBug.

I know GeoServer does not handle reprojecting features returned by WMS
getFeatureInfo.

Cheers,
F.
