I added the details to the bug report :) I need to understand better FilterEncodingPreProcessor, but after the test I did the other day, if we have a a filter of the form: and( id( fids ), anything .... ), we can use the low comppliance visitor to extract the anything filter, and the high comppliance visitor to extract the fid filter, right?

Just to be clear what I am trying for here is a "strict" setting that we can apply which would result in the correct behaviour... If a filter of the form: and( id( fids ), anything .... ) We will replace it and request just: id( fids) from the WFS And then handle "anything..." on the client side (inside the WFSDataStore). -- Jody Garnett On Monday, 11 April 2011 at 6:17 PM, Joaquín Rodriguez-Guerra Urcelay wrote: 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. De: Jody Garnett [mailto:[email protected]] Enviado el: sábado, 09 de abril de 2011 2:39 Para: Joaquín Rodriguez-Guerra Urcelay CC: [email protected]<mailto:[email protected]>; Justin Deoliveira; Gabriel Roldan 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). -- Jody Garnett On Friday, 8 April 2011 at 7:49 PM, Joaquín Rodriguez-Guerra Urcelay wrote: 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 100.82219958499486,57.14285725714286</coordinates> </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: LOW <?xml version="1.0" encoding="UTF-8"?> <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"; xmlns:gml="http://www.opengis.net/gml";> <ogc:And> <ogc:PropertyIsEqualTo matchCase="true"> <ogc:PropertyName>id</ogc:PropertyName> <ogc:Literal>1</ogc:Literal> </ogc:PropertyIsEqualTo> </ogc:And> </ogc:Filter> <?xml version="1.0" encoding="UTF-8"?> <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"; xmlns:gml="http://www.opengis.net/gml"/> MEDIUM <?xml version="1.0" encoding="UTF-8"?> <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"; xmlns:gml="http://www.opengis.net/gml"/> <?xml version="1.0" encoding="UTF-8"?> <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"; xmlns:gml="http://www.opengis.net/gml";> <ogc:FeatureId fid="FID.1"/> </ogc:Filter> HIGH <?xml version="1.0" encoding="UTF-8"?> <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"; xmlns:gml="http://www.opengis.net/gml"/> <?xml version="1.0" encoding="UTF-8"?> <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"; xmlns:gml="http://www.opengis.net/gml";> <ogc:FeatureId fid="FID.1"/> </ogc:Filter> are we on the right track? any close to the solution?
