Hi my friends,

I'm reading and writing vector feature attributes with OpenLayers using WFS
1.1.0 Protocol and got a problem as below.

As I found, when OpenLayers get feature attributes from server, GeoServer
returns an XML content in which if a field of feature class is empty,
returned XML does not list that field. So when I get value with that field
(myfeature.attributes["field name of empty field"] ) will return undefined.
And certainly, I can not assign value for that field.

This is the same problem for new feature has just been added, I can not
assign value for its fields.

I think OpenLayers has some methods to do above jobs, but currently I do not
know. I hope you will please to help me in this problems.

Thanks for your time!
