Adding a dev list discussion for this. It doesn't seem to have an easy fix. The reason for getting 4 notifications is cos you get a notification for operations on the internal structure, and internal data holder generation. So, for a a k,v put on /root, you'd get:

- "/" structure modified
- "/root" structure modified
- data in "/" initialized with empty map
- data in "/root" initialized with empty map

> A put operation to the TreeCache API causes multiple CacheEntryModified events to be fired. The data map (an AtomicHashMap) is always empty and does not contain the modifications. The notifications are fired twice for isPre=false and isPre=true, which means they are fired 4 times.
