False DescribeFeature Request URL in GeoExt QueryPanel

I got the GeoExt QueryPanel working so far, it recognizes the layers available on my Geoserver but it is not able to get the attribute columns for the dataset. I configured an osgeo proxy on my Apache Server, I use the override-ext-ajax.js and have theOpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url=";class configured.

A DescribeFeatureType request is sent when selecting the layer I want to filter. The same happens when trying to choose the attribute column in the query panel, but there are none displayed.

The sent request URLs look like this:

http://localhost/cgi-bin/proxy.cgi?url= http%3A%2F%2Flocalhost%2Fcgibin%2Fproxy.cgi%2Fwfs%3F VERSION%3D1.1.0%26REQUEST%3DDescribeFeatureType%26TYPENAME%3Dcases%26query%3D

The strange part here is, that the request is sent via the proxy.cgi twice. The request URL should look like this, going passed geoserver's WFS:

http://localhost/cgi-bin/proxy.cgi?url= http%3A%2F%2Flocalhost%3A8080%2Fgeoserver%2Fwfs%3F VERSION%3D1.1.0%26REQUEST%3DDescribeFeatureType%26TYPENAME%3Dcases%26query%3D

Does anybody have a clue what's going wrong here and why the request URL is wrong? The strange thing is that even if I remove the Open.Layers.ProxyHost class and the override-ext-ajax.js from my application, the request is sent that way. This leads to the conclusion, that the source of error can be found in the QueryPanel.js file, yet I couldn't spot it.

Can it, on the other hand be related to my server?

Other requests sent in the application (GET & POST) work fine. The (relevant) code looks like this, maybe you can spot the error.

OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url="; var owsUrl = "/geoserver/wfs"; var symbolizer =["default"]; symbolizer.graphicName = "square"; var store; Ext.onReady(function() { store = new{ url: Ext.urlAppend(owsUrl, "VERSION=1.0.0&REQUEST=GetCapabilities"), protocolOptions: {version: "1.1.0"}, autoLoad: true, listeners: { load: initApp } }); }); function initApp() { var vecLayer = new OpenLayers.Layer.Vector("Query", { eventListeners: { featuresadded: function() { var extent = vecLayer.getDataExtent() } } }); var queryPanel = new gxp.QueryPanel({ title: "Query", region: "center", width: 350, bodyStyle: "padding: 10px", autoScroll: true, layerStore: store, bbar: ["->", { text: "Query", handler: function() { queryPanel.query(); } }], listeners: { query: function(panel, store) { var rule = new OpenLayers.Rule({ filter: panel.getFilter() }); rule.symbolizer[queryPanel.symbolizerType] = symbolizer; var style = new OpenLayers.Style("", {rules: [rule]}); wms.mergeNewParams({ sld_body: new OpenLayers.Format.SLD().write({ namedLayers: [{ name: panel.selectedLayer.get("name"), userStyles: [style] }] }) }); store.bind(vecLayer, { initDir: }); } } });

At a quick glance I'd imagine the issue is around the lines below:

181 var protocol = record.get("layer").protocol; 182 this.attributeStore = new{ 183 url: Ext.urlAppend(protocol.url, Ext.urlEncode({ 184 "VERSION": protocol.version, 185 "REQUEST": "DescribeFeatureType", 186 "TYPENAME": record.get("name") 187 })),

The tricky part will be debugging. To find out exactly what is happening, I'd make sure you set up the following:

  1. Use the full source code, not a minified version, so you can debug it more easily
  2. Use Firebug in FireFox
  3. Put a debugger line just before the code above. The code will stop at this point and you can check the url values, and where they are coming from.

I figured the problem - think it was a setting that I made when having difficulties configuring a WFS. In GeoServer Globale settings, I set the Proxy Base URL tohttp://localhost/cgi-bin/proxy.cgi?url=
