Hi,
still in need of re positioning parent child object through Drag and drop function, I switch from nested grid to tree.
I use flat format who was more logical for me but I try both with same trouble :
https://jsfiddle.net/NearEarthObject/o879bfwg/One time again, child are moving without any trouble the one to the other.
But when I try reorganizing parent row, I got a console error : Cannot read property 'children' of undefined.
What is amazing, I took inspiration of
https://paramquery.com/pro/demos/dnd_tree example.
In this case that works fine.
Any idea how I could solve my issue ?
Thanks in advance
