Resetting the Ember app breaks with "cannot re-register: serializer:-default".

[kaukas]

Hello.

I am working on an Ember + Ember Data based application, writing some tests. Before each test I want to reset the whole application but right before the second test this leads to

Error: Cannot re-register: `serializer:-default`, as it has already been resolved.

What is the recommended way to reset the app? I cannot simply destroy and recreate the app as it is done in the Ember Data tests since the app is created once during the page load.

Thank you!

This does not fix the bug but the recommended way to reset the app is to destroy and recreate the app before each test. This is the default in Ember CLI. What breaks when you do this?

I can not destroy and create it again because the initializing code is part of the single page app which is called only once.

It appears that this is a known problem. Strange that I am still getting it with the latest version.

You should be able to destroy/create and initializers will be called again.

@kaukas what version of Ember are you using?

[kaukas]

@fivetanley, as I said I can not recreate the app. It's a SPA created once in initializers.

I am on version 2.2.0. I found out that

App.reset();

is not enough. Adding

App.buildRegistry();

solved the issue for me. It seems strange that buildRegistry is not part of reset but maybe the authors had their reasons.

In any case this is not an issue of Ember Data in particular. Closing it.
