[OpenLayers-Dev] Overwriting attributes

[Bart van den Eijnden (OSGIS)]

Hi Steven,

you should be able to do something like:

OpenLayers.Util.extend(OpenLayers.Format.WFST.v1.prototype.namespaces,
{foo: 'bar'});

the same trick applies to the readers:

OpenLayers.Util.extend(OpenLayers.Format.WFST.v1.prototype.readers.wfs,
{'foo': function(node, obj) { console.log(obj); }});

Best regards,
Bart
