Hi Ben,
Thanks for the reply. I did what you suggested with the geometry property types
and mapped it as (for example):
<AttributeMapping>
<targetAttribute>
iso19112:position
</targetAttribute>
<sourceExpression>
<OCQL>wkb_geometry</OCQL>
</sourceExpression>
</AttributeMapping>
But it only gets empty gml elements:
<iso19112:SI_LocationInstance gml:id="gazplaces.312925">
<iso19112:geographicIdentifier>WA100148359</iso19112:geographicIdentifier>...
<iso19112:position/>
</iso19112:SI_LocationInstance>
Should I be using the GeoServer trunk rather than 2.1.3, which I'm using? Or is
there something else that I'm missing?
Regards,
Andrew

GeometryTypeImpl to ComplexType
Andrew,
GeoServer/GeoTools geometries are atomic entities. Instead of trying to set
properties/attributes on parts of geometries, create geometries (for example,
from a database geometry column, using database functions) with srs set
correctly and let GeoServer unpack and encode them for you. The target
attribute in this case should be territoryOfUse. If this is a geometry property
type, you probably don't need targetAttributeNode as app-schema (with GeoServer
trunk) is now smart enough to search the substitution list (thank you Niels).
Second, your namespace prefix "19112" is invalid. Namespace prefixes must be
NCNames, and cannot start with a digit. They can contain digits but typically
start with a letter. For example, a valid prefix would be
"iso19112":
http://www.w3.org/TR/xml-names11/#NT-NCName
http://www.w3.org/TR/xml11/#NT-NameStartChar
Kind regards,
Ben.
