Call to undefined method Backend\Widgets\Lists::setFormValues about october HOT 2 CLOSED

Hi @wpluut

In v3.6, the relation controller will initialize all the necessary widgets, even if they are not used. In v3.5, it would try to guess whether they were used or not. This change was necessary to allow nested relations to function correctly.

The error can occur when an event previously provided a Form widget now gets a List widget. This can happen in the relationExtendManageWidget or relationExtendViewWidget method overrides in your controller.

There are two options:

• Check that the $widget is an instance of the expected \Backend\Widgets\Form class (backwards compatible).
• Change the override method to the new one based on the widget you expect, in this case, Form.

I hope this helps.

Hi @daftspunk,

Thanks!
Overriding relationExtendManageWidget to relationExtendManageFormWidget solved the issue.
