If I have a tree with itemIds
/topA
/topB/bottom
and I use changeItemId(topA, topB) then this leaves me with a tree with itemIds
/topB
/topA/bottom
how do I get
/topB
/topB/bottom
The ID is defined on per item base, so change of parent ID will not change IDs of child items automatically.
You can use getSubItems to get list of child items, and call changeItemId against each of them.
