Removing Fragment from fragmentArray fails on PUT request

[prabakaranfresh]

Creating, Updating and Deleting fragments in Fragment Array works fine for a new model (isNew: true)

On an existing model from server, deleting a fragment inside fragmentArray removes it from the model and setting hasDirtyAttributes to true. But while saving the model using model.save empty object is sent to server (Only on PUT Request)

// app/models/person.js
import DS from 'ember-data';
import { fragmentArray } from 'ember-data-model-fragments/attributes';
const { Model, attr } = DS;

export default Model.extend({
  name      : attr('string'),
  addresses : fragmentArray('address'),
  titles    : array()
});

// app/models/address.js
import attr from 'ember-data/attr';
import Fragment from 'ember-data-model-fragments/fragment';

export default Fragment.extend({
  street  : attr('string'),
  city    : attr('string'),
  region  : attr('string'),
  country : attr('string')
});

// Data from server
{
  "person"  : {
    "name"  : "Benedict Cumberbatch",
    "address" : [{
      "street"  : "77A Bleecker Street",
      "city"    : "New York City",
      "region"  : "New York",
      "country" : "US"
    }, {
      "street"  : "221B Baker Street",
      "city"    : "London",
      "region"  : "England",
      "country" : "UK"
    }],
    "titles" : ["Doctor Strange", "Sherlock Holmes"]
  }
}

I am removing one of the addresses from the fragmentArray

let addresses = this.model.get('addresses');
addresses.objectAt(0).removeFragment();
// Also Tried this =>
// addresses.objectAt(0).removeObject();
this.model.save();

After this the data sent to the server is an empty object

// Data to server
{}

When I remove any fragment from the fragmentArray, hasDirtyAttributes is set as true for the model and the fragmentArray. But no data was sent to server on PUT request using model.save()

Referred this Issue: Remove fragment from fragment array? But mine happens only on model.save()

I just want to bump this issue as I'm having a very similar problem. Is this related to the open PR referenced here? #338

[prabakaranfresh]

@joshuamanns My ember-data version is 3.10.0. Isn't the PR #338 is related to ember-data 3.13.0?

@prabakaranfresh Were you ever able to resolve this? It's still a blocking issue for me and I'm debating if I should create an entire workaround instead of using fragments.

[prabakaranfresh]

@joshuamanns I am having a workaround. I am forcing dirtyAttributes on removing fragments from fragments array.

addresses.map(address => address.send('becomeDirty'));
