(I've added the method mymethod() in the thread to find the right Thread in the
stack)
Conclusion : I think that to get the email() value of the contact, my app has
to fetch a parameter value (using another editing context).
Question, I replace
EOEditingContext _localContext = new
EOEditingContext();
_localContext.setUndoManager(null);
_localContext.lock();
with
EOObjectStoreCoordinator parentObjectStore =
new EOObjectStoreCoordinator();
EOEditingContext _localContext = new
EOEditingContext(parentObjectStore);
_localContext.setUndoManager(null);
_localContext.lock();
And it works ! Is it normal ?
