[OpenLayers-Users] WFS-T delete/update

[Arnaud Cogoluegnes]

I finally found a hack (well, I think it is) by reading the
OpenLayers.Format.WFS.js code. Seems the typeName attribute of the update
request is mapped with the OpenLayers.Format.WFS layerName property.

The WFS layer writer (a OpenLayers.Format.WFS object) is created on demand
when the commit method is called:

/* from OpenLayers.Layer.WFS */
if (!this.writer) {
  this.writer = new OpenLayers.Format.WFS({},this);
}

The option table is empty, so the layerName property is not initialized. So
after the WFS layer creation, I added:

if (!water.writer) {
  water.writer = new
OpenLayers.Format.WFS({layerName:'G4WD:tasmania_water'},water);
}

I don’t know if it's the correct way, but it worked (I would be happy to
know the correct way if it exists :-)  )

If I find anything about the DELETE request (the FID was missing), I'll let
you know

Cheers

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
