[Qgis-user] NullPointerException updating with WFS plugin

[Hilmy Hashim]

I get a java.lang.NullPointerException when I try to update an attribute on
a layer loaded using WFS. The WFS server is a Geoserver 2.0.2 with all wfs
methods enabled. I get the error when I click on the save button in
Attribute table. I tested my Geoserver with another application and it
updates alright.

How can I troubleshoot this?

My QGIS config: 1.8.0-Trunk rev 4aeb473 on OSGeo4W Windows 7 64-bit.

Here is the exception report from the pop-up:
