XML for WFS GetFeature query has invalid filter
-----------------------------------------------
Key: GEOT-2112
URL: http://jira.codehaus.org/browse/GEOT-2112
Project: GeoTools
Issue Type: Bug
Components: data wfs
Affects Versions: 2.5.0
Environment: GeoTools-based WFS client and non-GeoServer based WFS
server.
Reporter: Clive Butler
When a DefaultQuery/FeatureReader is created with a filter, the resulting WFS
GetFeature XML can be invalidly constructed with an extraneous empty filter
element nested inside the supplied filter. Some WFS servers (ionic for example)
return a service exception, whereas GeoServer ignores the extraneous element.
Filter:
[[ GEOM intersects POLYGON ((-81 31.5, -76.5 31.5, -76.5 36, -81 36, -81
31.5)) ] AND [ USEDESC = Military ]]
XML:
<?xml version="1.0" encoding="UTF-8"?>
<GetFeature xmlns="http://www.opengis.net/wfs";
xmlns:gml="http://www.opengis.net/gml"; xmlns:ogc="http://www.opengis.net/ogc";
