onMove receives inconsistent parentId and index

[davidnaas]

Inconsistent index
Cursor would imply new index should be 1 but is reported as 2

Inconsistent parentId
Cursor and node.willReceiveDrop indicates that a drop will NOT happen, yet parentId is that of the Box rather than Container

This behaviour only happens after first moving Slider into a Box, then out again. Somehow that Slider continues to receive the Box as the parent when being moved. It should also be noted that those boxes are internal nodes in all cases, i.e. children is always an array

Same here, moving a node from a nested node to another one get an incorrect index, then if you move the node inside the same level the index is correct.

Yes. Same here. onMove is giving incorrect position. at root level, if there are two nodes, it am getting position as 2 whereas it should have been 1.

Possible solution? instead of get the index from the args in onMove, yo can get the proper one from the tree state like this, where tree is the ref to the component.

tree.state.dnd.index;

I discovered that the problem in my case is when the node next position is above the old one, even to another level but always dragging it upward, then the index jump one step more.

Will try this

@surajair the index in the state has the same problem, dragging the node upward the index is increased by 1, you can calculate the direction getting the old rowIndex of the node from the tree instance

Same here. When I drag a node above or below itself, index value changes. According to the example, index is 0 on above but index is 1 on below. It moves under next element when index is 1 with a simple dnd logic. That case is completely blocking me.
