If a remove and save of a JSON tree happens really fast after each other, we sometimes receives an error
--------------------------------------------------------------------------------------------------------
Key: KERN-750
URL: http://jira.sakaiproject.org/browse/KERN-750
Project: Nakamura
Issue Type: Bug
Components: Content - other
Affects Versions: 0.4
Environment: Firefox 3.6
Reporter: Christian Vuerings
Fix For: 0.5

When we fire a delete and a createtree operation very fast after each other, we sometimes get the following exceptions (1 in 10 times):
404
Missing source NonExistingResource, path=/_user/a/ad/admin/private/my_sakai_state for delete
500
javax.jcr.InvalidItemStateException: 1f7045f9-d1bf-464a-ae1b-79ff88a889e3/{}uid has been modified externally
Oszkar and Simon suggested to have an extra parameter for the createTree operation such as :delete = true that would also delete the tree under there.
This would take care of this current issue and would bring back 2 requests into 1.
