[OpenLayers-Users] Whitespace in Value Passed to Filter

[Jerome A. Wendell]

I have a 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.  If the value
passed to the filter contains whitespace within it, nothing is returned.  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, that have the
attribute with the value that I am using that has whitespace.  Is there
anything that I can do to the filter so that the whitespace doesn't cause
the search to fail?  The applicable part of my code is below:

 

var filter = new OpenLayers.Filter.Comparison({

                type: OpenLayers.Filter.Comparison.EQUAL_TO,

                property: 'myproperty',

                value: 'myvalue'

  });

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);

                }

}

 

Any suggestions are greatly appreciated.

 

Thanks.
