I want to make a page with input fields from multiple entities but when I add the input fields of the second entities I get this error:
Widget must be read-only because it is connected to an associated attribute.
I can make it a reference selector but I want to add new values. How can I do this?
They are associated with a one-to-many.
But even when I change it to one-to-one I still can't edit the fields.
Are the entities already associated with each other?
If it is a one-to-one association, the you could add a nested dataview which retrieves the second entity via association. In the nested dataview you can then add the input fields.
