Hi list,
I'm having a strange behaviour when receiving data from getFeature request. I prepare a request that is intended to mark some parcels from two different layers (these layers are stored in Oracle Spatial). The request looks like:
<?xml version="1.0" ?>
<wfs:GetFeature service="WFS" version="1.1.0" outputFormat="text/xml; subtype=gml/3.1.1" xmlns:wfs="http://www.opengis.net/wfs" xmlns:ogc="http://www.opengis.net/ogc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/wfs ../wfs/1.1.0/WFS.xsd">

All the features that I want to mark using these filters are unique rows in Oracle Spatial. Using my Ajax app I get the following response:

The thing is that I get two features with the same 'id' (the two first features -> id 752) and same geodata and one of the requested parcels disappear (id-> 759). In DB table the id's are:
TABLE -> RecintosSigpac
Id | PROVINCIA | MUNICIPIO | POLIGONO | PARCELA | RECINTO
----------------------------------------------------------
752 | 1 | 1 | 1 | 20 | 1
----------------------------------------------------------
759 | 1 | 1 | 1 | 24 | 1
----------------------------------------------------------
780 | 1 | 1 | 1 | 1 | 1
----------------------------------------------------------
...
TABLE -> ParcelasSigpac
Id | PROVINCIA | MUNICIPIO | POLIGONO | PARCELA
------------------------------------------------
432 | 1 | 1 | 1 | 29
------------------------------------------------
470 | 1 | 1 | 1 | 5
------------------------------------------------
...
In other tests I've done it happens the same with the table ParcelasSigpac (the same case but changing roles), so maybe it's something I make wrong with the filters, or there's something special that I've to configure in the DB table.
Can someone, please, help me? It's really important because it's causing some troubles.
Thanks.
