I have changed „transient“ together with resolveProxies, because
else opening .genmodel shows me the nasty error “The opposite of a transient
reference
> must transient if it is proxy resolving”.
Unfortunately you are right: setting “transient” to true on the
storage side has the effect that the reference is not serialized at all.
I didn’t find a lot of information about the flags and there
conditions:
General meaning of the flags:
http://publib.boulder.ibm.com/infocenter/rtnlhelp/v6r0m0/index.jsp?topic=/org.eclipse.emf.doc/references/overview/EMF.html
Discussion about the “transient resolve proxies issue”:
http://dev.eclipse.org/newslists/news.eclipse.tools.emf/msg23116.html
I really don’t know what to do here, except removing the
non-storage end of the association or some more in-depth tricks in our resource
implementation.
Any ideas?
Reiner.

No problem, I think we didn't
duplicate any work ;-)
I will update the Excel sheet later.
I noticed that you changed the transient property on some of the references to
true (e.g. BoundaryEvent.attachedToRef). Was this done on purpose? If I'm not
mistaken, transient features won't be serialized, but these should be?

Hi Henning,
wow, this is funny. You sent you mail almost
exactly in the moment when I wrote my other one J . Thanks to the work
again – I agree with your proposals.
As I have already applied
some of the issues in your Excel, but not completely, I would ask you to update
it ones more to differentiate the fixed on non-fixed ones. And after you have
done your feature in the templates, we continue in a coordinated manner ;-)
Regards,
Reiner.
Hi
Reiner,
that's good news!

2.
For all those
references, check if the target type is abstract. If yes, remove the abstract
flag. If you like you could extend your Excel to mark those cases.
See
the attached document.
3.
It would be good
to store somewhere that the type was originally abstract to avoid users to
accidently create instances of it (e.g. in the editor). But EMF must be able to
create proxies of this type for sure. We could e.g. change use the genModel
“image” flag for keeping the information of former abstract classes.
We
could add another details entry to the ExtendedMetadata of these classes (e.g.
abstract -> true). Additionally, I suggest to change the template
FactoryClass.javajet to the effect that the create method for originally
abstract classes does not appear in the interface Bpmn2Factory and is not
public in Bpmn2FactoryImpl. Thus it can be created during deserialization
(which calls EFactory.create(EClass)) but is somewhat hidden to users.
ItemProvider.javajet will likely have to be adapted as well (@ collectNewChildDescriptors).
If you're OK with that, I'd try to tweak the templates accordingly.
Regards,
Henning
