Hello Joaquín:
I am following you across lists. WFS is an unsupported module, generally
meaning it does not meet the QA levels expected for GeoTools.
The "pom.xml" file
(http://svn.osgeo.org/geotools/trunk/modules/unsupported/wfs/pom.xml) lists two
contacts as module maintainer: justin and gabriel who I have CCed.
I had a look in the list of open issue for GeoTools WFS:
- http://jira.codehaus.org/browse/GEOT/component/11098
It shows a fairly large number of open issues; including a couple that match
what you are describing. The difference is that your email has enough details
that we could look into what is going on.
Here are the close matches:
- http://jira.codehaus.org/browse/GEOT-3151 Deegree 3 reports WFS-T seriously
broken (references UDIG-1673 )
- http://jira.codehaus.org/browse/GEOT-2112 XML for WFS GetFeature query has
invalid filter
- http://jira.codehaus.org/browse/GEOT-1013 FidFilter not working in WFS data
store?
- http://jira.codehaus.org/browse/GEOT-1499 WFSFeatureSource.getFeatures()
always returns empty set with ALL query
The first one is the best match (and links to UDIG-1673); it ends with the
following comment:
> I talked with Markus and by "nested filter" they mean a filter in which you
> mid fid filters with something else. Fid filters are supposed to be the root
> of the filter, they cannot be mixed with anything else in OGC filter (both
> versions).
> Solving the above it's a matter of splitting the filter and deciding which

So I would like to update this bug report with the details you have provided
(and maybe give it a better name so it is easier to find).

It's a major breakthrough. An authentic gaming
smartphone on the nation's most reliable network.
And it wants your games.
