[OpenLayers-Users] overwriting functions

[Paul Spencer]

Kevin,

although this is probably not what you want to do (as Chris said  
later in this thread), the reason why this is not working for you is  
that you need to change the 'prototype' of SelectFeature.

OpenLayers.Control.SelectFeature.prototype.downFeature = function 
(feature){
alert('Overwritten!');
};

Cheers

Paul
