[OpenLayers-Users] WFS-T update problem with namespaces

[2StepForward]

Hi List,

and thanks for answers on my questions. I agree with you, that it's realy
hard to deal with XML....
I have yesterday tried to write a work around for that namespace problem
like this:

Defines in my OL-code:

var wfs4 = new OpenLayers.Layer.WFS(
                "Info", "http://server/geoserver/wfs?", {
typename:'WFS:info', geometry_column:'the_geom'},
                {
                   maxResolution:'auto',
                   typename:'WFS:info',
                   featureNS:'http://www.own-namespace.de/wfs'  -> my own ns
of GeoServer for xml-schema 
                   featurePrefix:'WFS',                                       
-> additionaly definition of the prefix
                });


Changes in WFS-Layer.js by commit function:

if(!this.writer) {
...........................................
}
options.layerName = this.typename;   -> new
options.featureNS = this.featureNS;   -> new
options.featurePrefix = this.featurePrefix; -> new


Changes in WFS-Format.js by update function:

if(!feature.fid) {......}
updateNode.setAttribute("xmlns:"+this.featurePrefix, this.featureNS); -> new
updateNode.setAttribute("typename", this.layerName);

I now, it doesn't lock nice, but it works....... 
It will be good, if anyone write if it's a good way to change it like I have
above wrote it.

Thanks Klaus
