Notice: Undefined offset: 0 in weight_field_widget_form()

any suggestion for how to solve this ?

Check if default value is not null

This warning is a regression introduced by this commit, as part of this issue 🐛 Weight default value is an array, error when saving Fixed .

The problem here happens in the Manage field UI, when adding a new weight field. When you add a new field, weight_field_widget_form() receives an empty array in the $items parameters. The new (faulty) code added in the commit above doesn't check to see if the key 'value' exists.

The patch in #3 doesn't solve the warning. It does set the default value to 0, which is needed, but the warning persists.
