Hi, I'm trying to use app-schema with a target schema that, unfortunately, uses a DirectPosition as the feature "geometry". I don't have any control over the schema so I have to try and make it work anyways.
What I get overall is that my points are turned into their WKT representation when the GML encoding happens. Which is not what I want. Looking a bit more deeply I see that the attribute is correctly bound to DirectPosition: ComplexTypeImpl http://www.opengis.net/gml:DirectPositionType extends doubleList(axisLabels:NCNameList,srsDimension:positiveInteger,srsName:anyURI,uomLabels:NCNameList) but nowhere in the code there is an attempt to use converters to turn the JTS Point into a DirectPosition. Now, I tracked down the issue to XPath.convertValue: private Object convertValue(final AttributeDescriptor descriptor, final Object value) { final AttributeType type = descriptor.getType(); Class<?> binding = type.getBinding(); if (type instanceof ComplexType && binding == Collection.class) { if (!(value instanceof Collection) && isSimpleContentType(type)) { ArrayList<Property> list = new ArrayList<Property>(); if (value == null && !descriptor.isNillable()) { return list; } list.add(buildSimpleContent(type, value)); return list; } } if (binding == String.class && value instanceof Collection) { // if it's a single value in a collection, strip the square brackets String collectionString = value.toString(); return collectionString.substring(1, collectionString.length() - 1); } return FF.literal(value).evaluate(value, binding); } type is a complex type, but binding for some reason is exactly Collection.class, which results in the wrong code path being chosen (the right one, imho, would be the usage of the last line, FF.literal(value).evaluate(value, binding), which could be expressed also as Converters.convert(value, binding)). Now... does anybody know why the binding ends up being a collection instead of org.opengis.geometry.DirectPosition? I still haven't quite tracked down where the bindings are built...
