There was a problem hiding this comment.
the mutating error is fixed by the 2 other changes that create a shallow copy of children for localValue
but without this change, a strange bug appears :
Screen.Recording.2023-11-02.at.15.22.15.mov
on drag/drop, multiple updates occur :
- the child "test 2" gets updated with its now 4 children
- the parent "Plats cuisinés" gets updated with its now only 1 child "test 2" (but the value passed of "test 2" has only the 3 original children, not the now 4)
