problem saving embedded objects

[ms]

hello,

persisting embedded lists (OType.EMBEDDEDLIST) seems to work well, but
when trying to persist embedded enums/objects i get the following
error:

java.lang.IllegalArgumentException: Property 'protocol' of type
'EMBEDDED' can't accept value of type: class

still having issues when retrieving enums (svn trunk at revision
