Thanks for the issue. Are you able to provide a Stackblitz/repo with a reproduction of the issue? I am unable to reproduce this issue on my end. You can use this link as a base Stackblitz: https://stackblitz.com/edit/ionic-v4-angular-tabs

I have provided a Stackblitz of a working ion-input + forms demo here: https://stackblitz.com/edit/ionic-v4-angular-tabs-fmeseo.

Thanks!

Hi there,

In this Stackblitz I was able to reproduce all the issues and one more, when I use markAsTouched, the input not display the "red line".

Thanks 🙏

Apologies for the delay in response. I was able to reproduce this and will look into a fix. As a temporary workaround, you can set the disabled property directly on the ion-input rather than the ion-item. Thanks!

Hi there,

We are proposing some changes to form components that seek to resolve this issue. We would love your feedback on these proposed changes! You can read more about the changes and leave comments here: #25661

[liamdebeasi]

Thanks for the report. In Ionic 7 we will be introducing a new syntax for using form components such as ion-input. You can find a summary of the changes here: #25661

The reported issue is fixed with this new syntax. Work to update ion-input to use this new syntax has been completed, so I am going mark this issue as resolved. We plan to have a public beta period for Ionic 7 in the future. You can visit the Ionic Blog, Ionic Twitter, or our GitHub Releases Page to be notified when the Ionic 7 beta is released. Let me know if you have any questions. Thanks!
