[OpenLayers-Users] GetFeature with WFS protocol doesn't return features

[Lauri Kajan]

Hi Gery,

The execution never get that far. Featureselected is not triggered.
Problem is in the request method of GetFeature class or actually much
deeper but that httprequest code gets too complex for me to understand.

In the request method of GetFeature class result.features.length is 0 so it
never selects anything.

*Request method of GetFeature class:*
callback: function(result) {
if(result.success()) {
if(result.features.length) {
if(options.single == true) {
this.selectBestFeature(result.features,
bounds.getCenterLonLat(), options);
} else {
this.select(result.features);
}
