application view rerender(): Uncaught TypeError: Cannot read property 'append' of null

Stack:

Uncaught TypeError: Cannot read property 'append' of null
Renderer_insertElement
Renderer_renderTree (anonymous function)

Called from here (the anonymous function above):

// TODO: should be scheduled with renderer
        run.scheduleOnce('render', function () {
          if (view.isDestroying) {
            return;
          }
          view._renderer.renderTree(view, view._parentView);
        });

Erroring on this line:

    function Renderer_insertElement(view, parentView, element, index) {
      if (element === null || element === undefined) {
        return;
      }

      if (view._morph) {
        view._morph.setContent(element);
      } else if (parentView) {
        if (index === -1) {
>>>>          view._morph = parentView._childViewsMorph.append(element);
        } else {
          view._morph = parentView._childViewsMorph.insert(index, element);
        }
      }
    }

I'm trying to refresh all views after modifying locale translations for ember-cli-i18n.
The code I'm using to refresh the top level application view is:

Ember.$.each(Ember.View.views, function(i, view) {
                    if (view.renderedName === "application") {
                        view.rerender();
                        Ember.Logger.debug('rerendering application view');
                    }
                });

A few JSBin's:

• without an {{outlet}} http://emberjs.jsbin.com/rwjblue/263/edit?html,js (no errors, works properly)
• with {{outlet}} http://emberjs.jsbin.com/rwjblue/264/edit?html,js (errors when setting view.element in the renderer)
• with an {{each}} in an outlet view http://emberjs.jsbin.com/rwjblue/265/edit?html,js (errors setting _childViewsMorph in ContainerView)

I was unable to replicate the exact error that @zyllorion is reporting though (but clearly there are some thing to fix).

@zyllorion - Can you tweak one of my JSBin's above to trigger the specific error that you are getting?

@rwjblue this is a bug, the parent view destroys views connected to an outlet and when rendering again errors trying to reattach destroyed views

Hi!

I was updating an app from 1.7.1 to 1.8.1, and I found the same issue (or maybe another one).

With 1.7.1: rerender the application view works fine
With 1.8.1 or 1.9.1 : rerender throw an error: Error while processing route: XXX Cannot read property 'connectOutlet' of undefined
With canary: rerender works fine

Here is a simple jsbin to demonstrate how to reproduce my issue (just play with the set of script tags): http://emberjs.jsbin.com/naquvegali/3/edit
