Problems saving a previously saved object in Google App Engine (Java)

Question

I am having problems saving a previously saved JDO object to the data store in a Google application. Basically, in one servlet I create an object and save it. In another servlet, I read the object, set up a bunch of properties and tried to update it. Updating is done through a makePersistent call to the PersistenceManager. Excluded exception and no warnings. However, when I access the same object later, it is still in its original state.

PersistenceManager never closes between reading and updating (as specified in the Repository documentation )

The only thing that may differ from the example in the documentation is reading lists, but updates are performed for an independent object. There is nothing in the documentation that scares it off. Could this be a problem?

To complete the context, I try to do this only in Eclipse and have not tried it in AppEngine yet. Any suggestions on what might happen?
