[OpenLayers-Users] Possible bug with Protocol.WFS

Mon Feb 8 18:58:09 EST 2010

Hi all,

I've been working with a few people on #openlayers to help me out with a WFS
issue.  I'm posting this to the list because I may have found a bug in the
process.

So, at one point, I packaged some of my WFS output into an XML file and
tschaub wrote the following example for me (which worked,
http://astro.temple.edu/~tub09307/tschaub.html):

>                     url: "OpenLayers-2.8/examples/gml/test.xml",
>                     featureType: "v_stats_20090101_000000",
>                     featureNS: "http://192.168.0.20/geoserver/wms",
>                     geometryName: "the_geom"
>                 })
>             });
>
>             map.addLayer(traffic);
>             map.zoomToMaxExtent();
>
>         </script>
>         <form>
>     </body>
> </html>

I then modified it to this, which did not work:

>                 units: "m",

I found that the above code will work if you add srsName: "EPSG:900913" to
the WFS options.

Is this a feature/bug/magic, or me being silly?
