[OpenLayers-Users] WFS Not Returning Coordinates

[Arnd Wippermann]

Hi Roald,

Adding propertyNames (attributes of the feature) to the protocol solves the
problem with the geometry for MapServer 5.6.1. First I thought it wouldn't
work, because i added msgeometry instead of msGeometry. And I have to add
srsName to the protocol, what for version 5.2 is not needed.

thx
Arnd

Hi Blake,

You can work around this issue by providing the property names explicitly in
the options of your protocol, including the name of the geometry.
Example:

     propertyNames: 
'year,seq,name,storm_start,storm_end,msGeometry'.split(',')

Note that MapServer by default chooses 'msGeometry' as the name of the
geometry attribute even though it might be called 'the_geom' or
'wkb_geometry' on the data source. In your case it's 'location' I presume.

Regards, Roald
