[Geoserver-users] WFS transactionUpdateGeometry QGIS problem

emmexx · November 27, 2015, 12:05pm

I have a problem when I try to update a multilinestring geometry.
I had the same issue in the past, I thought I had solved it but now it is back again.

Setup: geoserver 2.7.1 and a test layer connected to a postgis table.

I connect to the layer in qgis.
I can create a new feature (line), I can update feature attributes but I can't update the geometry of any feature. If I add or move a node I get an error:

Transaction failed
org.geoserver.wfs.WFSTransactionException: Update error: java.lang.String cannot be cast to com.vividsolutions.jts.geom.Geometry

I enabled geoserver debug log and the xml transaction sent from qgis is the following:

I tried to execute it in the demo requests and got the same error.

So I compared the example xml request created by the demo with the one created by qgis and the only relevant difference is in the xmlns used in any tags or declared in the transaction tag.

So I started from a working xml request (based on the one generated by the demo) and modified the tags from the outer tag to transform it to an xml similar to the qgis-generated one. First I modified the transaction tag followed by the Update tag and so on.
The transactions were successful up to when I used the following xml:

The problem seems to be in the Value tag.
If the xml has <wfs:Value>...</wfs:Value> it works.
If I change it to <Value xmlns="http://www.opengis.net/wfs">\.\.\.</Value> I get the aforementioned error.

Any clue on what's wrong here?

thank you

I get the aforementioned error.

I asked the same question on the qgis users mailing list and received an answer that hints that the problem is in geoserver.

Can anybody tell me if I should file a bug?

Thank you

Yes, go ahead. The XML you have is pretty dumb (repeating the default
namespace at every tag
is really overkill) but it looks like it migh be valid. More investigation
needed, but I have no time
to work on it now.

So yes, open a ticket with all the details required to reproduce the issue
(if you can do include
a sample dataset you're trying to modify too)

Cheers
Andrea
