2.14.6 - Error loading relationships in templates You modified "X" twice

[urbany]

Hi, i just upgraded from: 2.13.2 to 2.14.6.

And now some templates where I was successfully doing:

{{ car.category }}

Where car is a model which has a category defined like: category: belongsTo()

Throws an error:

Assertion Failed: You modified "category" twice on <my-project@model:car::ember1007:1011> in a single render. It was rendered in "component:table-row" and modified in "component:table-row". This was unreliable and slow in Ember 1.x and is no longer supported. See https://github.com/emberjs/ember.js/issues/13948 for more details.

If i add {{debugger}} before that line in the template and try in the console get('car.category') I get the same error, but the second time it works correctly, can this be something to the new lazily load of relationships?

I am not sure, but this may be related to #4942

@kumkanillam thank you very much!
It's the same bug, so I'm gonna close this and follow that issue.
