You probably aren’t creating an ‘Adres’ object and associating the user to it. So, there is no object in the data view to edit, causing it to render as non-editable. To fix it, you’ll want to create an Adres object at some point in your workflow. If every user is expected to have one, you could do it when the user is created. If not, you could do it in a microflow before showing the page where they edit their address.
In general, when you run into a scenario where input fields are not editable but you can’t figure out why, there are 2 common causes:
Side note: there is a setting on Data Views called Empty Entity Message. If you fill that in, a data view containing an empty object will show that message instead of rendering as non-editable.
