Backbone.js Handling of Attributes That Are Arrays

Question

I really like Backbone, but I am having the hardest time doing what would seem to be simple things. I appreciate any help with the following example.

I have a model,

Answer 1

"defaults" can also be a function.

var Criteria = Backbone.Model.extend({
    defaults: function () {
        return {
            "status": "Normal",
            "priority": "Normal",
            "tags": new Array()
        }
    }
});

This would create a new array when a new Criteria is instantiated. See: http://backbonejs.org/#Model-defaults
