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

[Gery .]

Hi Lauri,

not sure but the problem can be related to how the features are called (and thus stored) to be then selected. If featureselected never gets triggered, that should mean that it is not called. The callback you show what actually does? I think taking a look to the whole code will be more useful.

Regards,

Gery

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);
                        }

perhaps using some:

console.log("WHAT IT IS GOING ON WITH": feat);

console.log("WHAT IT IS GOING ON WITH": bbox);

console.log("WHAT IT IS GOING ON WITH": center);


can help you to find the error.

Hello,
When I'm trying to use GetFeature control to get features from my WFS run into problems. The "featureselected" event never gets triggered.
I debugged it little bit and found out that the wfs request itself return a valid gml and the status code of the request is 200. But still the features array of the result object is empty so the code never gets to the select method of the GetFeature class.


Is this something to do with a proxy that I have set?I have set OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url=";
I have configured GetFeature control as follows:


    var select = new OpenLayers.Control.GetFeature({        protocol: OpenLayers.Protocol.WFS({                    url:  "**:8080/geoserver/wfs",
                    featureType: "**",                    featureNS: "**",                    geometryName: "geom"                }),                click: true,

                clickTolerance: 1,                single: true,                hover: false     });    select.events.register("featureselected", this, function(e) {

        var feat = e.feature;        var bbox = feat.geometry.bounds;         var center = bbox.getCenterLonLat();         map.panTo(center);     });



I would appreciate all the helpThanks

-Lauri
