Thank you Jody,
Yes, please update the report, or I do it if you prefer, the only thing is that
I think I dont have priviledges to change the name of the bug report, do you?
I will try to play a bit more with FilterEncodingPreProcessor to see If can I
get any farther.

Asunto: WFS Filter composed by fid filter and comparation filter not being
accepted by mapserver
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/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 part
of it to send the remote wfs.
Anyways, there is a bigger issue... who's going to fix this one? No
maintainer....
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).

Hello list
This is the first time I write here, so hello everybody :)
I have recently started to work in a project using uDig, which works with
geotools.
The other day I was having an issue with a filter udig was sending to a wfs
layer. The filter is a fid filter, but geotoool's streaming renderer is adding
a bbox filter to it, and mapserver is not understanding it probably due to an
encoding issue.
This is the filter sent by udig to mapserver (failing it due to the filter tag
contained in the main filter tag):
http://localhost:8080/cgi-bin/mywfs?SERVICE=WFS&VERSION=1.0.0&request=getfeature&typename=PositionReal&Filter=
<Filter>
<And>
<Filter>
<FeatureId fid="PositionReal.3"/>
</Filter>
<BBOX>
<PropertyName>point</PropertyName>
<Box>
<coordinates decimal="." cs="," ts=" ">-100.82219958499486,-57.14285725714286
100.82219958499486,57.14285725714286</coordinates>
</Box>
</BBOX>
</And>
</Filter>
And this is what mapserver understands:
http://localhost:8080/cgi-bin/mywfs?SERVICE=WFS&VERSION=1.0.0&request=getfeature&typename=PositionReal&Filter=
<Filter>
<And>
<FeatureId fid="PositionReal.3"/>
<BBOX>
<PropertyName>point</PropertyName>
<Box>
<coordinates decimal="." cs="," ts=" ">-100.82219958499486,-57.14285725714286

</Box>
</BBOX>
</And>
</Filter>
Joddy Garnett helped me in the udig-devel list and he suggested that it could
be an encoding issue, and maybe using the FilterEncodingPreProcessor we could
fix it.
I have tried to understand the FilterEncodingPreProcessor, but I am having some
dificulties. I have created a filter composed by a fid filter and a comparation
filter. My goal is to have them encoded on the same xml filter, but no luck. I
have tried the 3 compliance levels, hoping that after accepting each visitor
(one for each level) in the filter, I would be able to invoke visitor.getFilter
and obtain the new filter, hopefully one of them encoded as I want. So I
printed the xml code of the getFilter() filter of each visitor, but I guess I
didnt unerstand this correctly, right?
CODE:
org.geotools.xml.Configuration conf2 =D new
org.geotools.filter.v1_1.OGCConfiguration();
FilterFactory2 factory = CommonFactoryFinder.getFilterFactory2(null);
String fid1 = "FID.1";
Filter fidFilter= createFidFilter("FID.1");
Filter normalFilter = CQL.toFilter("id = 1");
Filter filter = factory.and( fidFilter, normalFilter);
FFilterEncodingPreProcessor visitor1 = new
FilterEncodingPreProcessor(XMLHandlerHints.VALUE_FILTER_COMPLIANCE_LOW);
FFilterEncodingPreProcessor visitor2 = new
FilterEncodingPreProcessor(XMLHandlerHints.VALUE_FILTER_COMPLIANCE_MEDIUM);
FFilterEncodingPreProcessor visitor3 = new
FilterEncodingPreProcessor(XMLHandlerHints.VALUE_FILTER_COMPLIANCE_HIGH);
System.out.println(""LOW");
FFilters.accept(filter, visitor1);
org.geotools.xml.Encoder encoder = new org.geotools.xml.Encoder(conf2);
encoder.setIndenting(true);
encoder.setIndentSSize(2);
encoder.encode(visitor1.getFilter(), org.geotools.filter.v1_1.OGC.Filter,
System.out );
encoder = new org.geotools.xml.Encoder(conf2);
encoder.setIndenting(true);
encoder.setIndentSize(2);
encoder.encode( visitor1.getFFidFilter(), org.geotools.filter.v1_1.OGC.Filter,
System.out );
System.out.println(""MEDIUM");
Filters.accept(filter, visitor2);
encoder = new org.geotools.xml.Encoder(conf2);
encoder.setIndenting(true);
encoder.setIndentSize(2);
encoder.encode( visitor22.getFilter(), org.geotools.filter.v1_1.OGC.Filter,
System.out );
encoder = new org.geotools.xml.Encoder(conf2);
encoder.setIndenting(true);
encoder.setInddentSize(2);
encoder.encode( visitor2.getFidFilter(), org.geotools.filter.v1_1.OGC.Filter,
System.out );
System.out.println(""HIGH");
FFilters.accept(filter, visitor3);
encoder = new org.geotools.xml.Encoder(conf2);
encoder.setIndenting(true);
encoder.setIndentSize(2);
encoder.encode( visitor3.getFilter(), org.geotools.filter.v1_0.OGC.Filter,
System.out );
encoder = new org.geotools.xml.Encoder(conf2);
encoder.setIndenting(true);
encoder.setIndentSize(2);
encoder.encode( visittor3.getFidFilter(), org.geotools.filter.v1_1.OGC.Filter,
System.out );
OUTPUT:

</ogc:Filter>
are we on the right track? any close to the solution?
Thank you!
Joaquín
