Thanks for that. Still got a javascript issue though.
Suppose I extend linearRing with the swapXY method - call it linearRingEx.
The code calling context though is:
} else if (filter.type ===
OpenLayers.Filter.Spatial.INTERSECTS) {
var geom = filter.value;
transformGeometry(geom);
geom.components[0].swapXY();
params.cql_filter = 'INTERSECTS(SHAPE,'
+ geom.toString() + ')';
To call the swapXY method, I need to somehow cast the geom object (a
superclass) so that the linearRing descendent is of linearRingEx. I am
struggling to see how to do this in JS.
