[OpenLayers-Users] Feature attribute editing/updating

[Jean-François Gigand]

Strange... The method is missing from the apidocs!

The current 2.11 apidocs are complete:
http://dev.openlayers.org/docs/files/OpenLayers/Control/SelectFeature-js.html

I just checked, it does exist (2.10 and 2.11):
OpenLayers.Control.SelectFeature.prototype.unselect (as well as
"select").

>> 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?
