I'm using your django-treebeard app to work with trees on my application. So I've detected when I work with a tree with many leafs and branchs and I need to delete an entire branch, I run the method .delete() but I perceived that the data existent inside database is not being removed from there. So If I need to put a new branch at the same old place, an error appear at the system:
IntegrityError at /salesflow/json/site/manage/
(1062, "Duplicate entry '0001000100010001' for key 'path'")
Trying to insert after root > node 1 > node 2
Can you give a clue how to solve this?
