[OpenLayers-Users] WFS-T not saving

Mon Feb 21 11:16:46 EST 2011

Dear list,

I'm trying to set up a simple WFS-Transactional example with GeoServer
as my WFS server for a Point Layer from a Shapefile.
WFS works: I can see the right points within my data's boundingbox.
But when I press the save button, the saveSuccess callback is fired,
but nothing gets saved.

The Problem seams to be that OpenLayer is sending no changes to the
server, GeoServer log says:

Request: transaction
	handle = null
	service = WFS
	version = 1.1.0
	baseUrl = http://localhost:8080/geoserver/
	providedVersion = null
	lockId = null
	group = []
	insert = []
	update = []
	delete = []
	native = []
	releaseAction = ALL

What's wrong here? Do I have to create or save my points in a
different way? Any idea?

Many thanks for your help,

Björn
