Can't swap currentView of Ember.ContainerView in a #each - ember.js

Question

I'm trying to use the the currentView feature of an Ember.ContainerView in the context of a #each helper but it fails when currentView property is changed to another view.
My aim here is to allow editing an item of a list, by changing the regular view to an edit view when the user click a link.
Main template:
<ul>
{{#each itemController="person"}}
<li>{{view Ember.ContainerView currentViewBinding="cv"}}</li>
{{/each}}
</ul>
Template 'name' used to display a person :
{{firstName}} {{lastName}} <a {{action edit}}>edit</a>
Controller for the currentViewBinding property ('cv') and handling for the edit action.
App.PersonController = Ember.ObjectController.extend({
cv: Ember.View.extend({
templateName: 'name'
}),
edit: function() {
this.set('cv', Ember.View.extend({
templateName: 'nameEdit'
}));
}
})
'nameEdit' template corresponding to the view that needs to be displayed to edit the person object.
{{input type='text' value=firstName}} {{input type='text' value=lastName}}
The api guide says that:
When the currentView property is set to a view instance, it will be added to the ContainerView. If the currentView property is later changed to a different view, the new view will replace the old view.
But it's worse if I replace the cv property with a view instance (by using create() instead of extend()) as a re-render error is yield. See this question of mine.
Here is the jsFiddle to play with http://jsfiddle.net/fblanvil/tD3Ph/3/

Answer 1

I ended up not using ContainerView at all and using a simple if. But it doesn't explain why it's not possible to use a ContainerView this way in an #each helper. If someone thinks it's worth a Jira, put a comment and I'll do it.
<ul>
{{#each itemController="person"}}
<li>
{{#if editing}}
{{view templateName='nameEdit'}}
{{else}}
{{view templateName='name'}}
{{/if}}
</li>
{{/each}}
</ul>
Simple and effective after all...
App.PersonController = Ember.ObjectController.extend({
editing: false,
edit: function() {
this.set('editing', true);
}
})
