Chris Beams commented on JDO-522:
---------------------------------

The javadoc for both PM and PMF setCopyOnAttach() methods includes:

+    * With this flag set to <code>false</code>, detached parameter
+    * instances are attached directly and change their state from
+    * detached to persistent-clean and from detached-dirty to
+    * persistent-dirty.

I believe it would be clearer if it read "from detached-clean to persistent-clean", instead of "from detached to persistent-clean"

I've made this change to:
    * With this flag set to <code>false</code>, detached parameter
    * instances are attached directly and change their state from
    * detached-clean to persistent-clean or from detached-dirty to
    * persistent-dirty.

Now waiting on JPOX to say they're ready for the checkin.

Attach (makePersistent) a detached instance always merges changes into the cache. Can this behavior be changed to make the parameter instance change its state, throwing an exception if there already is an instance in the cache, based on a user-specified property? Seems like this would be a good addition to the spec. AI Chris prepare a
