Hi peter do not check NewList we will remove it for sure!
*NOW:*
In general, the drag and drop behavior, the API, and the overall behavior is broken to a various degree and inconsistent between ListModel, it's children and related classes (TreeModel, NewListModel). Last week I was working on a File Dialog replacement https://github.com/peteruhnak/file-dialog and the brokenness and inconsistencies were really frustrating. I imagine
I don't see a point in trying to write a book about this particular section because it's really bad right now.
Of course not having a dedicated maintainer of Spec makes life a lot harder, as people that work with/on Spec generally invest into Spec at their own time discretion (me included), so while bugs can generally be fixed, there's really no systematic effort in cleanup and API harmonization.
I know And you see I did not know how to find a path. This is still on my todo to start renaming Model ->Presenter. But I'm working on a project proposal that I should finish :)
With Stef we started to clean up and rethink it a bit when I was in Lille because there's a lot of things we don't like or should fix, but that's a long-term plan. We need a more immediate solution for the current mess. -_-
*TL;DR:* 1. imho no point in documenting this stuff _right now_ 2. it's seriously broken 3. we need to clean it up and harmonize first

Hello I would try to integrate the exemple Drag n Drop from http://spec.st/docs/drag_n_drop/ at the tutorial Building UI with Spec, so I have create a class in Pharo to try them and modify the code.
I have found some of problems, I'm not sure if it come from strange configuration (i think about dragTransformationBlock: ), but it appear on the both version (my class and the original code).
Marion,
1) Reproduce: Deplace the 'c' in the list of int, try to replace the 'c' in the list of char Error "nil not found in Orderred Collection" - Proceed don't remove the c from the list and make arrives a nil, like in the result deplaceReplaceC.png - Abandon seems work well, but the next refreshing of the list (by another move) make the nil appear too
2) Reproduce: Deplace the 3 in the list of char, try to replace the 3 in the list of int (at its place) Error " '3' not found in Orderred Collection" - Proceed duplicate the 3 gives the result DuplicateNumber.png - Abandon affect all number after the place, they "become" the previous number (BadNumber.png). Try to move the 4 make an error because it don't found 3, try to move the 5 make move the 4.
3) Reproduce: Deplace all items the list of int in the other Try to move the 'a' in the empty list of int Error "SubscriptOutOfBounds: 0" - Proceed remove the a from the list, but don't make it appear - Abandon seems work well
