multiple views of the same data causes elements to stay hidden

[benkuper]

Hello,
in this very simple REPL, I'm showing two list referencing the same items (the real use case is 2 views of the same data, one tree view and one arranged in layout).

Most manipulations in this example break one list Linked List bug REPL

This is not expected to work. What is the expected behaviour? When I drag over an item in list A should elements in list B make room for it as well (even though it won't land there)? If you want to sync two lists, you can do it after drop (finalize handler)

so I should duplicate the lists ?
my goal is simple, I have a [potentially huge] data structure that is showing a custom dashboard interface. There is an tree view showing all the individuals elements of this dashboard, and a canvas where all those elements are laid out.
The idea is that I'd like to be able to swap elements in my tree view and that would reflect automatically on the board view, and vice versa. Ideally I could even take one from a view and drop it in the other view but that would be a bonus.

You can sync them using a store or any other method but do it on drop, not while the list is in a temp state during drag

Well my goal is to only use one list, so I'm not syncing anything special, like in the REPL.

So you say I should check if it comes from one or the other and not update if it's not the good one ? because right now they have basic behaviour which I though was only used when touching them, but something is happening to the actual list that makes the other view's items go invisible.
I actually have the same problem when drag'n'dropping from a toolbar to the list.
It's a bit late at home but I'll show you my use case. I think it would be great to not have to duplicate the lists, but I understand if it's not compliant with the lib's design.
Thanks for the time and work !

If you're able to show a minimal example of synced views of same data, I think it could be interesting for other people (and I've not seen any other lib do that as well)

for more context you can check the current build here : Golden Board
if you play a bit with it you'll find many several broken behaviours. I tried to be as close as possible to practices learnt on this github but I guess this use case is a bit edgy.

the clean repo for this is here : https://github.com/Golden-Geek/GoldenBoard
