Cannot call writableTag after the object is destroyed. (in acceptance tests)

[MartinMalinda]

Power select makes tests randomly fail for me. The error does not occur when the acceptance test is run alone, but only when run in a series of other tests. It seems like something is not getting cleaned up.

"ember-power-select": "^1.8.4",
"ember-source": "~2.13.0-beta.1",
"ember-cli-qunit": "^3.1.2",

I am using the selectChoose helper.

export default (startAt, endAt, optionIndex) => {
  run(() => {
    fillIn('.email', 'malindacz@gmail.com');
  });

  clickDatePicker('.startAt', startAt);
  clickDatePicker('.endAt', endAt);

  andThen(() => {
    run(() => {
      selectChoose('.new-booking-form', '.ember-power-select-option', optionIndex);
    });

    run(() => {
      click('.new-booking-form [data-save-button]');      
    });
  });
}

It may or may not be related to some PublicAPI call..?

I will try different versions of PS and Ember to see if it makes any difference.

The You modified XXX twice in a single render is usually a symptom of another thing erroring. But I have never seen this writableTag thing before.

My only suggestion is that, since selectChoose is async, you might want to put the folloing click in another andThen. That is the only possible source of race condition I see, assuming it's not related with the datepicker.
