MT>> No this is currently not possible, Teneo assumes that all eobjects belong a registered
epackage. If you enter a bugzilla for this then I can see what I can do. But to be realistic, it is
a fair amount of work so it will take a while (> 1 month) before I can pick this up.

MT>> Hmm, I would need to debug this to see what happens. For one reason or another my news reader
(thunderbird) gets confused by your post. So I see the attachment content inline and can't download
them. Can you send them to me directly (mtaal@elver.org)?
But for jpox the same limitation as for hibernate applies, the epackage to which you refer should be
registered with Teneo.

MT>> The id which you get back from the IdentifierCacheHandler can be used as a normal id in
hibernate. Note the identifiercachehandler only works if your objects have stayed in-memory all the
time. So for example if you send them over the wire (in a client-server scenario) and get them back
then it won't work (as the object is a different instance in memory).

Hi Daniel,
There is currently no manual workaround for this. Can you open a bugzilla for this and attach your
example to it? As said in the other post it can be some work and I am not sure if I have time to do
this before eclipsecon but I will do my best.
