Actually this "cache" doesn't have to be invalidated when the sitetree changes, because the tree object is always updated with the changes. When you create a new document, a new node is first inserted into the in-memory representation of the sitetree, and then this sitetree is saved to the xml file. When you call getTree() the next time, you should get the updated tree object without re-reading it from the file. Well, that's how it should work. Of course this doesn't explain your problem... Sorry if that's not much help, I have no idea what's going wrong.
