Changing number of rows resets Values in form elements in ListView

Hey, so I created a dynamic using a listview and form elements (select, etc). I dynamically change the number of rows in the list view. When I do that it removes the currently inputted elements in the form. That seems like a bug to me. That can lead to very unintended behaviour where a user increases the number of rows and then all her inserts into the forms are lost.

Hey @lys123! Sorry for the delay here, missed this one :slight_smile:

This is definitely on us, although I’m not sure it’s a bug as much as a bad UX. What I think is happening is that we’re re-rendering the whole ListView component when the number of rows changes, which is why your inputted data is disappearing. Either way, I filed it with the eng team - can’t promise a timeline but when we get to it I’ll post in the thread!

awesome. Now i have to tell my users to always save before adding an element. It works but… is error-prone haha

@lys123 - it seems I spoke too soon. You can use the ListView’s row keys feature to make sure that your inputted state gets kept!
