Hi,
I have a very simple shp file with AZIMUTH field. Same point can have
different azimuth directions. So for example point Y with three directions
will be described as three rows with different GID, different azimuth and
same geom.
I apply SLD (see below) that will show available azimuths for a given
point. SLD works fine when a layer comes from oracle spatial or PostGIS but
behaves strange with shapefile. It will render only the first row for a
given point, i.e. will show only one direction and skip other two. If I
delete first row for the point it will rerender and display second azimuth
and ignore the last one (so data is actually there). I tried the same with
square symbol but I get the same result.
Tested with geoserver 2.1.2, 2.1.3, 2.2-rc1
