Sorry, should have read more closely. Geoserver doesnt honour srsname in
this context (Mapserver does). You have to convert the geometry to
server native projection at the client end.
eg my code implementing a pt selection using DWITHIN. transformgeometry
function does the work of converting to native.
ptSelCtrl[i] = new
OpenLayers.Control.DrawFeature(selectedLayer, OpenLayers.Handler.Point);
ptSelCtrl[i].events.register("featureadded", this,
function (e) {
clearData();
var geom = map.getExtent(); //Done with left side
only to avoid 180 line crossing issues
var pt1 = new OpenLayers.Geometry.Point(geom.left,
geom.bottom);
var pt2 = new OpenLayers.Geometry.Point(geom.left,
geom.top);
transformGeometry(pt1);
transformGeometry(pt2);
var dist = (pt2.y - pt1.y) / 200;
var pfilter = new OpenLayers.Filter.Spatial({
type: OpenLayers.Filter.Spatial.DWITHIN,
distance: dist,
distanceUnits: "meters",
value: e.feature.geometry
});
var ly = getLayerNode(combo.value);
if (ly.CQL && ly.CQL != '') {
var format = new OpenLayers.Format.CQL();
pfilter = new OpenLayers.Filter.Logical({
type:OpenLayers.Filter.Logical.AND,
filters:[format.read(ly.CQL),pfilter]
});
}
wfsProtocol[combo.value].read({
filter: pfilter,
callback: processSpatialQuery,
scope: strategy
});
});
mapPanel.map.addControl(ptSelCtrl[i]);
transformGeometry has application-specific code to sort out what map
projection is and what the native projection is, and then transforms with:
geometry.transform(proj, pproj);
