bug: datetime previous / next month button trigger's twice

[mread1208]

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

• v4.x
• v5.x
• v6.x

Current Behavior

When you try and navigate between "previous" and "next" months, the calendar event triggers twice. For example: If I'm on February and I select the "Next" arrow (>), instead of being taken to "March" I'm shown "April". The issue also happens with the "Previous" button where if I'm on February, and I click the "Previous" arrow (<), I should be taken to January 2022, but I'm instead taken to December 2021.

If I roll back to @ionic/angular: "6.0.0", the issue goes away, but as soon as I bump past @ionic/angular: "6.0.1" the issue shows up again. Looks to be something introduced around that time (as that's when ionic core version was bumped to 6.0.5).

Expected Behavior

Clicking on the Previous / Next arrows should only navigate a single month instead of double.

Steps to Reproduce

You can see this very issue on the Ionic Framework Docs page by clicking on the previous / next arrows on any of the examples: https://ionicframework.com/docs/api/datetime. I also created a Stackblitz below.

Code Reproduction URL

I created a StackBlitz using Angular 13 with @ionic/angular: "6.0.1" that highlights the issue.

Thanks for the issue. I'm going to close this as a duplicate of #24712. This has been resolved with #24713 and the fix will be available in the next Ionic release. In the meantime, you can downgrade to Ionic 6.0.4 as a workaround.

how can we downgrade to 6.0.4 version ?

npm install @ionic/[email protected] ? this will work

[averyjohnston]

Yup, exactly 👍

[mread1208]

Yes, that will do the trick, but I noticed this issue happening on 6.0.1, 6.0.2, 6.0.3 and 6.0.4... I actually had to roll mine back all the way to 6.0.0:

npm install @ionic/[email protected]
