Thanks for the information, I will create a bug report next week.
I was able to solve the ordering problem with another GeoTools change,
but this one is a bit of a kludge.
In org.geotools.gml3.bindindings.PointTypeBinding.parse() the order of
the coordinates is being used irrespective of any coordinate reference
system.
I switched the order to get them to work.
The code is below:
public Object parse(ElementInstance instance, Node node, Object
value)
throws Exception {
if (node.hasChild(DirectPosition.class)) {
DirectPosition dp = (DirectPosition)
node.getChildValue(DirectPosition.class);
return gFactory.createPoint(new
Coordinate(dp.getOrdinate(1), dp.getOrdinate(0)));
}
if (node.hasChild(Coordinate.class)) {
return gFactory.createPoint((Coordinate)
node.getChildValue(Coordinate.class));
}
if (node.hasChild(CoordinateSequence.class)) {
return gFactory.createPoint((CoordinateSequence)
node.getChildValue(
CoordinateSequence.class));
}
return null;
}
While I completely agree that the order should be based on the
coordinate reference system, I do not believe that is being considered
in the current state of the code.
I will create a bug report for this also.
In addition, we were able to identify cases in GeoServer where the a
parent feature's coordinates where ordered in one way and a child's
feature coordinates were transposed in a single complex query.
Thanks,

In order to get someone to review your patch could you kindly create a
bug report.
With respect to lay/lon being tansposed - it is a very common problem
(mostly because each user has a different idea of what order it should
be in; please check your coordinate reference system object, look at the
axis - the order defined there should match your data). I should note
that this issue is not specific to geotools - it is a plague on our
industry called lack of metadata :)

I have an application that queries a GeoServer (2.0.1) that
contains complex features using GeoTools 2.7 M2.
I have successfully integrated the simple features into the
application leveraging a wfsDataStoreFactory
I have begun processing the Complex Features and have run into a
couple of issues.
We encountered a bug in Application Schema parsing code - I have
attached a potential fix.
Essentially, org.geotools.gml3.ApplicationSchemaXSD threw a
NullPointerException when attempting to process relative includes when
parsing the schema.
This fix has eliminated the problem and I am now faced with
another issue with the latitudes and longitudes being transposed.
When I user the method below to get the Point geometry, the X
and Y coordinated are transposed in the Point object from where they
were when I used this method with the wfsDataStoreFactory.
public static Point getPointGeometry(Feature feature) {
Point point = null;
GeometryAttribute geometryAttribute =
feature.getDefaultGeometryProperty();
if (geometryAttribute != null) {
Object geometryValue =
geometryAttribute.getValue();
if (geometryValue instanceof Point) {
point = (Point) geometryValue;
}
}
return point;
}
I have queried for wfs version 1.0.0 and 1.1.0 and receive the
same results for both.
Any help would be appreciated.
I can create and post a test program in the next couple of days,
if this will help.
Thanks,
