Cannot create Views dynamically

[Myslik]

Maybe I am missing something, but probably since 626a4e7#L1R922 I am no longer able to create views dynamically with templateName specified.

App.MyView.create({ templateName: 'tempname' }).render();

This snippet fails saying it cannot find the template specified. It is the smallest piece of code that should reproduce the error. I have found out that in function templateForName is container undefined in this case.

I need to dynamically create views in my custom ContainerView.

I have looked inside your view tests and you are defining the container when creating the view. It is the preferred scenario right now?

@Myslik in most situations you should be using this.createChildView, this setups of the childView correctly.

see https://github.com/emberjs/ember.js/blob/master/packages/ember-views/lib/views/view.js#L2058 for more details.

That being said, we should be giving helpful deprecation warnings rather then this rather opaque error.

@Myslik this should help: ecbd0bf

Thank you, I have missed that method.

@stefanpenner, I don't understand how to arrange this code in order to use createChildViews...

App.ModalView = Ember.ContainerView.extend({
    childViews: ['modalHeaderView', 'modalBodyView'],

    modalHeaderView: Ember.View.extend({
        templateName: 'modal/modal_header'
    }),

    modalBodyView: Ember.ContainerView.extend({
        currentViewBinding: 'controller.currentView'
    })
});

For now I have the error thrown in templateForNamebecause of a undefined container...

@dogawaf on master, there should be not error just a deprecation warning.

@dogawaf I tried to replicate your issue @ http://jsbin.com/ucanam/21/ but was unable to. Can you continue from the jsbin, and demonstrate the issue? Just ping back on this thread once you have it... I will help you sort this out.

Hi @stefanpenner

I have updated the jsbin. I've got the deprecation warning, and the assertion failure. http://jsbin.com/ucanam/22/
You can see that my modal is rendered through a {{render}}. I don't know if this is relevant...

[stefanpenner]

@dogawaf bdffb37 should fix your issue, please confirm.

[dogawaf]

Yes it did. Thanks a lot.
