I am using GeoServer and OpenLayers. I have an OGC filter setup to be used on a WMS layer. The filtered features are being placed on a vector layer. As long as the value that I pass to the filter does not contain any whitespace, the filter works fine, and the features are returned by GeoServer. If the value passed to the filter contains whitespace within it, nothing is returned by GeoServer. I am using Firefox with Firebug to test the map, and all of the values that are passed to the filter are shown correctly in the POST command. I know the features exist on the layer that is being filtered, so the problem is with the filter when the value contains whitespace. Below is the portion of my code used to make the request:
var filter = new OpenLayers.Filter.Comparison(
{ type: OpenLayers.Filter.Comparison.EQUAL_TO, property: ‘myproperty’, value: âÂÂmyvalueâ }
);
wfsProtocol = new OpenLayers.Protocol.WFS(
{ version: “1.1.0”, url: “http://myserver:8080/geoserver/mystore/wfs”, featureType: “mylayer”, //name of the geoserver layer featureNS: “mystore”, //name of the geoserver store geometryName: “the_geom”, srsName: “EPSG:4326”, scope: strategy }
);
var strategy = new OpenLayers.Strategy.Fixed(); var response = wfsProtocol.read(
{ filter: filter, callback: processWFSQuery }
); function processWFSQuery(response) { try {
var gmlParser = new OpenLayers.Format.GML.v3();
var features = gmlParser.read(response.priv.responseXML);
vectorLayer.destroyFeatures();
if(features.length > 0) {
for(var i = 0; i < features.length; i++)
{ var feature = features[i]; feature.geometry.transform(new OpenLayers.Projection(‘EPSG:4326’),this.map.getProjectionObject()); vectorLayer.addFeatures(feature); }
layextent = vectorLayer.getDataExtent();
map.zoomToExtent(layextent);
}else {
alert(“Not found!”);
if (popup)
{ popup.destroy(); }
}
} catch(e)
{ alert("Error: " + e); }
}
I am using a shapefile data store. The post request for the feature that is found is as follows:
XML

I get the same type of response for any features that have whitespace within the value passed to the filter. Both of the features in the requests above exist in the shapefile. In the layer preview of GeoServer I can perform the search and both features are found.
If you need any additional information, please let me know.
