Hi Jaroslav, I think the Article entity returned was detached already, right? In fact you can try a simple test by modifying the returned object and verify it value on Admin Console.
The PersistenceManagerFactory takes time to init, but once only ( http://code.google.com/appengine/docs/java/gettingstarted/usingdatastore.html ) while it's cheap to create as many PersistenceManager's as your need.
