isDirty/isPristine don’t trigger computed property changes

[PVSAmulya]

After updating ember-changeset-validations from 2.2.1 to 3.16.0, the computed properties that are dependent on changeset.isDirty are not updating when changeset.isDirty changes. This doesn't appear to be an issue for the other computed properties. Properties on the changeset that contain modified values trigger computed properties as expected.

Here is the project that recreates the issue. isDirty/isPristine computed properties do not get triggered. firstName property does get triggered as expected.

When using ember-changeset 3.15.0 with ember-changeset-validations 2.2.1 changeset.isDirty computed property works as expected. I debugged this issue to validated-changeset.

There was a similar issue in ember-changeset for isValid/isInvalid that has been resolved. https://github.com/poteto/ember-changeset/issues/455

@PVSAmulya I pulled down your repo and removing the computeds fixes the issue. There is some lack of compatibility between Ember's old push based vs today's pull based reactivity. We did add the dependentKeyCompat. However, I took a brief look at ember-changeset and validated-changeset and unsure why exactly it isn't working for isDirty or isValid.

I know this solution might not be feasible on a really large project. But generally native getters for many of the use cases would be preferred.
