    I’m trying to create a generic editor page in an Ember.js app. I need to create a few TextFields to bind to attributes on a model, but I will only know at runtime what fields this model has. My controller has an field called metadata, which describes the fields for this generic editor form. I want to iterate over the contents of this metadata and build up the form directly. Essentially I’m trying to do this:{{#each row in metadata.rows}}{{#each element in row.elements}}{{element.fieldName}}: {{

    What is the ember.js community recommendation for reporting Ember app crashes? I’m looking for the equivalent of the exception_notifier gem in Rails so that I can be notified if users are experiencing errors.This Stack Overflow post recommends generic javascript error handling solutions including:Handle window.onerror yourself Use a hosted service that handles window.onerror for you like Airbrake.io or MusculaI’m hoping there is some kind of Mixin that gives you all this error handling code, an

    Given Ember reached 1.0.0 recently, I wanted to start using it with tests. I’m using Yeoman 1.0 with Karma. I want to unit test models but I’m finding it very difficult to accomplish isolation.The example I have now is:describe(“Expense”, function() {return it(“has a computed property called `explained`”, function() {var expense = App.Expense.create({name: “My first expense”,value: 34});return expect(expense.get(“explained”)).to.equal(“My first expense — 34”);}); });As of 1.0.0, I get the follo

    I have a small application where I’m getting translations json for a locale and updating Ember.STRINGS. Am I doing something wrong? $.get(“http://localhost:8000/translations.json”, {locale : locale}, function (data) {Ember.set(‘STRINGS’, data) ; });In 0.9.5 I was doing Ember.STRINGS = data; and it seemed to work. When I changed it to 1.0.0 a lot of things started crashing around. Both of these don’t work. Ember.STRINGS = data ; Ember.set(‘STRINGS’, data) ;

    Using Ember js, I’ve got a tree-based structure of views, each of which has a text box. Entering text in any of the boxes and hitting ‘enter’ should add a ‘reply’ to that view; that is, add another view, indented via <ul>, underneath the original view.Problem is, when I hit ‘enter’, ember just crashes with an error at line 1 of the ember.js script. Any ideas what the problem could be?JS Fiddle here: http://jsfiddle.net/TcgJB/1/

    What’s the best practice regarding managing different types of state? For example I have an app where some state makes sense to be tied to a route so I’m using the router, but other states can’t be reflected in the URL and it wouldn’t make sense to do so. Is it ok then to have some state managed by the full router and other state managed by an instance of state manager? Is it acceptable to have multiple state managers or is that a bad idea?

    Regarding the new Ember.js routing system (described here), if I understand correctly, views are destroyed when you exit a route. Is there any way to bypass destruction of views upon exiting a route, so that the state of the view is preserved when the user re-enters the route?Update: Looks like, views are not destroyed unless the outlet view is being replaced in the new route. For e.g., if you are in stateA with ViewA in some {{outlet master}} and you go to stateB with ViewB in {{outlet master}}
