[Bug]: IgcDatePicker - igcChange event is not triggered when the clear button is clicked

[mkamiishi]

Which component(s) are affected?

Date picker

Description

For IgcDatePicker with mode="dialog", igcChange event is not triggered when the clear button is clicked.

Reproduction

1. Go to the sample https://codesandbox.io/p/devbox/damp-sun-q624vl?workspaceId=ws_Wca1rSR5QWnYWuPzcJ6uNq
2. Click the clear button on IgbDatePicker.
3. Observe the browser console.

Actual Result:
No output on the console.

Expected Result:

Workaround

I have worked around this problem by templating a clear button.

Is this a regression?

No or unsure. This never worker, or I haven't tried before.

Browser/OS/Node environment

As a side note, this is reproduceable regardless of the current mode the date picker is configured in.

There is no question there should be some kind of event, but I am not sure the igcChange is the right one since it is fired after change to the value is committed, usually when the component loses focus after user interaction.

Firing igcChange is technically incorrect, not to mention that when the user moves focus away from the date picker, it will be doubled.

A possible event to emit here can be igcInput or a brand new one that correctly carries the intent of the operation.

Thank you for your input.
I agree that igcChange should not be triggered on the clear button click regardless of the calendar display mode since the change is not yet committed as that moment.
One point that still concerns me is that for the datePicker with mode=dropdown, igcChange gets trigged on blur after clicking the clear button whereas for the one with mode=dialog, the event is not triggered at all.
Would that still be considered as a bug?

Yes

There is a pull request that fixes the issue with the igcChange event not being emitted in non-editable configurations of the date picker input - dialog mode, readonly/non-editable state.

As for the behavior when clicking the clear button, I suggest opening a new feature/enhancement issue where we can discuss with the team how to proceed as this will be closed once the pull request is merged.
