[OpenLayers-Users] Feature attribute editing/updating

[Jean-François Gigand]

Hi,

I'm not sure to understand what you expect upon updateAttributes() :

- update feature style (if it depends on attributes):
   call feature.layer.drawFeature(feature)

- save the attributes back to PostGIS:
   for that you need OpenLayers.Strategy.Save
   (with OpenLayers.Protocol.WFS), or maybe you do it with custom code/protocol

- unselect the feature (and close the popup)
   just call selcontrol.unselect(feature)

...
What do you need to do exactly?

Note: the example you mentioned seems a bit old (2.6 or 2.7). It may
be all right but be aware of it!
