Override js file from admin

Hello guys,
How I can override the file /AdminBundle/Resources/public/js/pimcore/object/helpers/import/configDialog.js ?
Thx in advance

Check http://prototypejs.org/learn/class-inheritance.html

You should be able to use

var newDialog = Class.create(pimcore.object.helpers.import.configDialog, {
 // your redefined methods
});

Disclaimer: Never tried that and beware you may break things.
