Hi,

please check examples\wfs-protocol.html for the right way to do this as of
OpenLayers 2.8.

Best regards,

>         "&TYPENAME=aster_gdem",
>         "&OUTPUTFORMAT=GML2"].join(",")
>         );
>
>     map.addLayers([wms, test_WFS]);
>
>     map.zoomToMaxExtent();
> }

> The test_WFS layer is not displaying and I don't know how to fix it.
