Hi Terry,

If you call the abort() method on your connection,
and your PersistentDict has changed by some other
client connection, the PersistentDict will be put into
the "ghost" state.
You can check that by calling the _p_is_ghost() method
on your PersistentDict.
If it has changed, you should access the PersistentDict
items in some way to get the revised version loaded
into memory so that you can detect subsequent
changes.

Does  this help in your situtation?

As for _p_changed, yes, it is reset on every commit().

David
