This control is used to select points from a layer. If layer is
geoserver, then works fine.
pointSelectControl[i].events.register("featureadded", this, function(e){
var protocol = new
OpenLayers.Protocol.WFS.v1_1_0({
url:
layerobj[0].layers[combo.value].spatialQuery[0].url,
geometryName: "SHAPE",
featurePrefix:
layerobj[0].layers[combo.value].spatialQuery[0].featurePrefix,
featureType:
layerobj[0].layers[combo.value].spatialQuery[0].featureType,
srsName: (projstr=="EPSG:900913" &&
(layerobj[0].layers[combo.value].serverUrl.search(/arcgis/)>=0)) ?
"EPSG:102113" : projstr
});
clearData();
protocol.read({
filter: new OpenLayers.Filter.Spatial({
type:
OpenLayers.Filter.Spatial.DWITHIN,
distance:
map.getExtent().getHeight() / 10000000,
distanceUnits: "m",
value: e.feature.geometry
}),
callback: processSpatialQuery,
scope: strategy
});
});
This generates:

|If layer is arcgis, then I get exception:

exceptionCode='InvalidParameterValue'><ows:ExceptionText>The spatial operation

element).</ows:ExceptionText></ows:Exception></ows:ExceptionReport>
Anyone got idea on what this error means?
Oddly, polygon selection works and works whatever distance units I put in.
