[OpenLayers-Users] WFS-T delete/update

[Arnaud Cogoluegnes]

Thanks for your replies.

I found some hints for the update by analysing the GML request. Seems the
layer is incorrect in the request:

<wfs:Transaction xmlns:wfs="http://www.opengis.net/wfs" version="1.0.0"
service="WFS">
<wfs:Update typeName="features">
....

Indeed, "features" is not the layer address. With the correct typeName
(G4WD:tasmania_water) it worked (I tried with the GeoServer request demo
form).

Here some snippets of my code:

/* getting the layer */
var water = new OpenLayers.Layer.WFS(
  "Water", 
  "/geoserver/wfs",
  {typename: 'G4WD:tasmania_water'},
  {
    typename: 'tasmania_water', 
    featureNS: 'http://www.mapmap.org/g4wd', 
    extractAttributes: false
  }
);
/* the modify control */
/* first some options */
var modifyOptions = {
    onModificationStart: function(feature) {
        OpenLayers.Console.log("start modifying", feature.id);
    },
    onModification: function(feature) {
        OpenLayers.Console.log("modified", feature.id);
    },
    onModificationEnd: function(feature) {
        OpenLayers.Console.log("end modifying", feature.id);
        /* the UPDATE state is modified here!!!! */
        feature.state = OpenLayers.State.UPDATE;
    },
    onDelete: function(feature) {
        OpenLayers.Console.log("delete", feature.id);                    
        
    }
};
var modify = new OpenLayers.Control.ModifyFeature(water,modifyOptions); 
map.addControl(modify);

I then use the commit method of the WFS layer. So, anything I missed in the
use of OpenLayers API?

Thanks!

Arnaud

Hi Arnaud,

I didn't use the WFS-T functionnalities for a long time now. I hope I
can throw an eye on it, but I don't think I will have time soon.
However, don't hesitate to send snippets of code so that I can
reproduce your test case.

Regards,
Pierre
