[mapserver-users] SLD with LayerFeatureConstraints

[Meine Toonen]

Hi list,

I'm currently trying to filter features from a layer via a SLD, but using the style defined by the service. I managed to get a NamedStyle by defining a classgroup and assigning the class with the group. 

When I set the style via SLD to mv2, it works perfectly, but when I add the filterpart (LayerFeatureConstraints) it fails: the default style is used and no filtering occurs.

Am I doing something wrong, of is filtering nog possible via LayerFeatureConstraints?

Mapfile:

layer
  name telpunten_motorvoertuig_punt
  CLASSGROUP "mv"
  metadata
    "wms_title" "telpunten_points"
    "gml_include_items" "all"
    "wfs_featureid" "id"
  end
  group telpunten
  status off
  type point
  dump true
  template bla  
  connectiontype postgis
  connection CONNECTIONSTATEMENT
  data "locatie from (select id, nummer, locatie, coalesce(soort,'Onbekend') as wb_soort, wegnummer from telpunt ) as foo using srid=28992 using unique id"
  projection
    "init=epsg:28992"
  end
  classitem wb_soort

  class
    NAME "motorvoertuig"
    group "mv"
    expression "MOTORVOERTUIG"
    style    

        symbol "square"
        color 0 204 204
        outlinecolor 0 0 0
        size 8
    end
  end
  
  class
    NAME "motorvoertuig2"
    group "mv2"
    expression "MOTORVOERTUIG"
    style    

        symbol "square"
        color 255 0 0
        outlinecolor 0 0 0
        size 8
    end
  end


  processing "CLOSE_CONNECTION=DEFER"
end

The SLD:

                    </ogc:PropertyIsEqualTo>
                </ogc:Filter>
            </sld:FeatureTypeConstraint>
        </sld:LayerFeatureConstraints>
    </sld:NamedLayer>
</sld:StyledLayerDescriptor>


  Thanks in advance!
