Problem Persisting Objects

[kouphax]

The following bit of code extends your people example and attempts to add a new person by using $$(person) to extend the object and create new instances of the object. It seems I need to call persist each time or I get the error below. Either I am doing wrong (most likely) or there is a bug in the $$ method?

Error

Uncaught TypeError: Cannot read property 'adapter' of undefined
    agility.fn.persist.save
    e.extend.proxy.gjquery.js:16
    $$.controller.click #add:53317/:51
    e.extend.proxy.gjquery.js:16
    Mjquery.js:16
    f.event.handlejquery.js:17
    f.event.add.i.handle.k

Code

(function(){
    var person = $$({}, '<li data-bind="name"/>').persist($$.adapter.restful, {collection:'people'});

    var people = $$({
        model: {},
        view: {
        format: 
            '<div>\
            <span>Loading ...</span>\
            <button id="load">Load people</button><br/><br/>\
            <button id="add">Add Person</button><br/><br/>\
            People: <ul/>\
            </div>',
        style:
            '& {position:relative}\
            & span {position:absolute; top:0; right:0; padding:3px 6px; background:red; color:white; display:none; }'
        }, 
        controller: {
        'click #load': function(){
            this.empty();
            this.gather(person, 'append', 'ul');
        },
        'click #add': function(){
            var p = $$(person, {name: "New Person"}).persist($$.adapter.restful, {collection:'people'});                      
            p.save();
            this.append(p, "ul");
        },
        'persist:start': function(){
            this.view.$('span').show();
        },
        'persist:stop': function(){
            this.view.$('span').hide();
        }
        }
    }).persist();
    $$.document.append(people);
})();

Thanks for reporting this. It should be fixed in upstream, so you can remove .persist() from:

var p = $$(person, {name: "New Person"}).persist($$.adapter.restful, {collection:'people'});
