How to override a singleton?

[Dumas]

How can I cleanly extend the Ext.data.Validations singleton?


The following code is not working, it returns a Sencha-internal error:

Ext.define('Bancha.data.override.Validations', {
    override: 'Ext.data.Validations',
    fileMessage: "is not a valid file",
    file: function(config, value) { ... }
});
//error: Object [object Object] has no method 'override'  at sencha-touch.js:6595

Is this a bug?

Thanks

You can do this via:

Ext.define('Bancha.data.override.Validations', {}, function() {
    Ext.apply(Ext.data.Validations, {
        fileMessage: "is not a valid file",
        file: function(config, value) { ... }
    });
});
