[OpenLayers-Users] WFS layer - commit works, save strategy from WFSProtocol does not work!!!! POST vs GET ?!?!

[paweluz]

Hi!
I have a really strange problem. At the beginning I was thinking that it was
Geoserver fault, or maybe Postgis but now I think this is Openlayers fault.

At first I was using WFS layer, I had implemented insert, update, delete and
modify functions and everything was was working just great. But since WFS
layer is deprecated, I started using vector layer with WFSProtocol. And it
does not work!!!

With WFS layer I use something like this 
feature.state = OpenLayers.State.INSERT;
mylayes.commit();

In this case my data was successfully in the database.

In Vector layer I used WFSProtocol. Now when I do :
saveStrategy.save();

But I got response in the firebug.
<?xml version="1.0" encoding="UTF-8"?>
<ows:ExceptionReport version="1.0.0"
  xsi:schemaLocation="http://www.opengis.net/ows
http://localhost:8080/geoserver/schemas/ows/1.0.0/owsExceptionReport.xsd"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <ows:Exception exceptionCode="InvalidParameterValue">
    <ows:ExceptionText>Error performing insert</ows:ExceptionText>
  </ows:Exception>
</ows:ExceptionReport>

Can anyone please explain to me this. How come WFS.commit() works but
savestrategy does not? I know for sure that my code in openlayers is wright.
You may see it in my previous topic: 
http://n2.nabble.com/SaveStrategy-does-not-work-WFSProtocol-with-Vector-Layer-PROBLEM-WITH-POSTGIS-td4762666.html#a4762666

Maybe the reason is that WFS layer use just GET method, and Vector Layer
(WFSProtocol) uses POST method... Can anyone please help me??

Regards,
Poul
