i get sometimes on an update operation of my node a InvalidItemStateException()

item cannot be saved because it has been modified externally.
and i dont know the reason and how i can reproduce it ?
can somebody explain me the reason ?
the message "the item cannot be saved because it has been modified
externally." means
that the item is stale, i.e. another has session has modified it.
Property p1 = (Property) session1.getItem("/some/property");
Property p2 = (Property) session2.getItem("/some/property");
p1.setValue("foo");
p2.setValue("bar");
p2.save();
p1.save(); // throws InvalidItemStateException
you can avoid this by locking the parent node.
