Problems with the widget in update action controller

[waml0478]

I have problems with the widget when the form performs the action update. When I make an update in the form, the field that uses the widget appears empty even if it contains information and only allows the modification if a new item is added.

I need that when doing the update, in the field the previously selected items are shown and I do not force myself to add a new item.

Same for me. It is impossible to figure out what actually user did with the file: deletion and doing nothing looks exactly the same for the server (as an empty payload).
This made the widget completely useless for update actions..
