Your worker thread almost certainly needs its own database connection(s): applicaiton code typically relies on the isolation provided by connection-per-thread, which means that it is not "safe" in general to share persistent objects between threads. Assuming that you do grab a connection and get its root object, you should then be able to traverse to your friendly local site manager, calling 'setSite' at *each* parent site manager you pass along the way. > I'm aware of ITask's but unsure if developers are supposed to use them > for their own purposes?
