Hi Stefan,
Sorry to hear that you have all these issues.
Regarding issue 3 and 4, I checked this in cvs on the 15th of june. So this should be solved in the
next build, or can you cvs?
I also solved another issue related to cdopackage persistence. So maybe this is related to one of
your other issues....
btw, I cross-posted to the emf newsgroup because cdo is graduating/has graduated.
gr. Martin

Hi Stefan,
I'm answering to Martin's comment to reduce noise in the EMF newgroup.

Yes, unfortunately it's currently intentional since we are not allowed
to ship non EPL compatible stuff and we didn't find a better way so far
to use 3rd party components like Hibernate. Can you please open an
enhancement request where we can discuss alternative approaches. The EMO
legal department will want to have a chance to review possible
solutions, too.

I digged a bit but have no explanation so far. Please open a Bugzilla so
that you can track progress.

I'd need to know more about your activator and its plugin. Can you
please open a Bugzilla and attach code so that I can reproduce the
deadlock (is it reproducible?).

> store one Dummy instance in the Database
Is there a stack trace or a log message?
I can't see how this problem relates to bug #230387 since that one is
about multiple packages and not about packages with only interfaces. Can
you please explain why you see a relation here?
I suggest that you enter a new Bugzilla to track this issue.

IIrc. Simon, Martin and I discussed this or a similar problem some time
ago. I even believe that this was fixed already. Simon, Martin, can you
remember if we have a Bugzilla/fix for this?
> Should I open bugs for these issues?
See above.
> Can you provide quick fixes to my two stoppers?
I (and Martin) believe the two stoppers are already fixed. Martin, right?
For the other issues I have just created a 1.0 maintenance branch to
beat the boredom ;-)

Hi Eike,
Yes I think that a number of the issues below have been fixed in cvs (and your latest maintenance
build). So it would be great Stefan, if you could try the latest build.

Sorry, I haven't been precise on that one.
I was referring exactly to the case in bug #230387 but it seems that the
problem I described there was initially described to general.
Added an attachment note about this to the bug.

Again, I'll revisit this one with the current version.

Hi,
new comments below ...
>> Issue 5:
>>
>> When calling getOrCreateResource() in a plugin activator's start()

Well, that was a problem in 0.8.0 in a rather complex scenario. I just
tried 1.0.0 with my simple scenario and was not able to reproduce.
I'll keep this one in mind and will open a bug if I come across it again.
I am now able to execute this once:
public void writeObject() {
System.out.println("resource now contains " +
Activator.getDefault().getResource().getContents().size() + " products");
Product p = Model1Factory.eINSTANCE.createProduct();
p.setName("test");
p.setVat(VAT.VAT0);
Activator.getDefault().getResource().getContents().add(p);
Activator.getDefault().getTransaction().commit();
}
When the testcase ends and the process terminates, I start the same
thing again and get a:

I'll have to include this into the automated build, too ;-(

Hi Martin, Stefan,
I propose the following fix in TeneoHibernateMappingProvider:
| *protected *List<EPackage> resolveSubPackages(EPackage ePackage)
{
*final *List<EPackage> result = *new *ArrayList<EPackage>();
resolveSubPackages(ePackage, result);
*return *result;
}
*private **void *resolveSubPackages(EPackage ePackage, List<EPackage> result)
{
EPackage globalPackage = EPackage.Registry.INSTANCE.getEPackage(ePackage.getNsURI());
*if *(globalPackage != *null*)
{
ePackage = globalPackage;
}
result.add(ePackage);
*for *(EPackage subEPackage : ePackage.getESubpackages())
{
resolveSubPackages(subEPackage, result);
}
}|
Stefan, if you file a Bugzilla, I can commit this fix, or do you want
to, Martin?
Cheers

Hi Eike,
Fine for me, the getEPackage is ofcourse the correct one (I used get, assuming that the EPackage
registry would only contain EPackages...).
Regarding that the subpackages are not checked against the registry anymore. I agree that the change
that a subpackage is registered before the parent package is very unlikely (if not impossible), so
your proposal below is correct afaics.
Can you check it in?

Done: https://bugs.eclipse.org/238300
Btw. the hanging of the client in case of a server processing failure is
the expected behaviour. It should be gracefully finished by a timeout
expiration.

Hi Eike, hi Martin,
I updated to head and found an issue not directly like my initial issue
7, but seems kind of related. See below:

The code leading to this is, as in my previous tests:
| @Test
*public **void *writeObject() {
System.out.println("resource now contains " + Activator.getDefault().getResource().getContents().size() + " products");
Product p = Model1Factory.eINSTANCE.createProduct();
p.setName("test");
p.setVat(VAT.VAT0);
Activator.getDefault().getResource().getContents().add(p);
Activator.getDefault().getTransaction().commit();
}|
It is executed without error the first time.
When the test runs the second time (on the DB initialized the first
time) I get the error. (BTW line 14 - the line triggering the error is
still the |getResource().getContents().size()|). (seems to be the
..size() operation)
If you need a trace, I can do one for you. (Just let me know which
components).
Is this related to a known bug or should I open a new one?
Cheers
Stefan

Hi Eike, hi Martin,<br>
<br>
I updated to head and found an issue not directly like my initial issue
7, but seems kind of related. See below:<br>

With all of these workarounds, I get to store and read my models in one
session alright.
<br>
However, when I close my application and reopen it, initialization
fails consistently when trying to get the contents of a resource:
<br>
getResource("/test").getContents() seems to not initialize the thread
context variables on the server:
