Chained ListEditors

[almagnit]

I have multiple entities with a one-to-many relations, such as:

A { List<B> b; }

B { List<C> c; }

C { some fields }

I'm trying to edit these entities by the editors

AEditor extends Editor {

 BListEditor b...

}

BListEditor implements IsEditor<ListEditor<BProxy, BListEditor.BItemEditor>>{

  BItemEditor implements Editor<BProxy>{

    CListEditor c...

  }

}

CListEditor implements IsEditor<ListEditor<CProxy, CListEditor.CItemEditor>>{

  CItemEditor implements Editor<CProxy>{}

}

In the UI it looks like:

A - Container with fields and list of items B(list of grids)

B - Container with combobox and grid - C

C - editable grid

So when I try to edit an already saved data it works fine.

But if I dynamically create B and C, then while saving list B.c == null

Why RF doesn't send list of CListEditor?

Is obtained that the object B was added to the object A, and object C still remains in the array editedProxies

From the code you sent me by mail, the problem is that you're editing B with a 'null' c and then call listEditor.setValue(newList) as an attempt to assign B.c. This won't work.

You have to assign a non-empty list to B.c before you edit it (i.e. just after the context.create(B.class), before you hand the B proxy to the list for editing).

This is because the list passed to ListEditor#setValue is modified in-place, it's never assigned to the edited field. This is the same for all editors with the exception of LeafValueEditors.

Big thanks Thomas You're absolutely right
