Gabriel Roldán reopened GEOS-2039:
----------------------------------
reopening sine a wrong assumption in JDBCDataStore that filter == preFilter
makes the defect still appear for postgis
> Invalid FID filter results in invalid query, should result in an emtpy
> feature collection instead
> -------------------------------------------------------------------------------------------------
>
> Key: GEOS-2039
> URL: http://jira.codehaus.org/browse/GEOS-2039
> Project: GeoServer
> Issue Type: Bug
> Components: WFS
> Affects Versions: 1.6.4, 1.7.0-beta1
> Reporter: Andrea Aime
> Assignee: Gabriel Roldán
> Fix For: 1.7.2
>
>
> Trying to use a FIDFilter whose structure does not conform to one expected by
> the FIDMapper in use results in invalid queries, such as:
> {code:xml}
> <?xml version='1.0' encoding='utf-8' ?>
> <wfs:GetFeature xmlns:gml="http://www.opengis.net/gml";
> outputFormat="GML2" service="WFS"
> xmlns:ogc="http://www.opengis.net/ogc"; maxFeatures="1" xmlns=""
> xmlns:wfs="http://www.opengis.net/wfs"; version="1.0.0"> <wfs:Query
> typeName="gisnet3:geonote_point" xmlns:gisnet3="http://gisnet3";>
> <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc";>
> <ogc:FeatureId
> fid="geonote_point.nfm--49e4e129_11b0c9f16f7_-7f5b"></ogc:FeatureId>
> </ogc:Filter>
> </wfs:Query>
> </wfs:GetFeature>
> {code:xml}
> results in:
> {code}
> Could not aquire feature:org.geotools.data.DataSourceException: Error
> Performing SQL query: SELECT "id", "title", "decription", "type",
> "links", "image_links", "video_links",
> encode(asBinary(force_2d("the_point"),'XDR'),'base64') FROM
> "public"."geonote_point" WHERE () LIMIT 1
> Error Performing SQL query: SELECT "id", "title", "decription",
> "type", "links", "image_links", "video_links",

> ERREUR: erreur de syntaxe sur ou près de « ) »
> {code}
> This is a limitation in the sql encoders design. The FIDMapper can throw an
> exception when going back from the FID to the attribute values, the sql
> encoder should just remove the featureid from the lot and if the fid filter
> becomes empty, replace it with a Filter.EXCLUDE instead.
