Removing nodes does not compact the IDs

[funforums]

Hi all,

It seems to me that the removing a node from the tree does not adjust the IDs of the nodes. This would be okay, if only adding a child to a node did not use length as a value for the ID of a new node being created.

E.G.
root with 3 children, (A,B,C)
ID A: 0/0
ID B: 0/1
ID C: 0/2
length:3

Calling B.remove() will leave the tree in this state

root with 2 children, (A,C)
ID A: 0/0
ID C: 0/2
length:2

Adding a new node D:
root with 3 children, (A,C,D)
ID A: 0/0
ID C: 0/2
ID D: 0/2
length:3

This results in element D disappearing from iterations over the tree.
