Hello,

I try to upgrade from teneo 1.0.0 to teneo 1.0.1 into my project.
The problem is that on initialization, I have a DuplicateMappingException.
If I ask the hbm, I see that all my resources are duplicated ...
With teneo 1.0.0, I don't have this problem. It is quite strange, isn't it ?

Thomas

Hi Thomas,
Yes this seems indeed as a strange problem. What you mean is that in the hbm the mapping for each
(e)class occurs twice?

Hi Martin,

How are you going ?
I mean when I call dataStore.getMappingXML(), I have twice the <class
entity-name ... > into the response.
I was used the lastest release (23 sept 2008)

I am going fine :-).

Can you post the hbm here or email it to me?

Hi Thomas,
I got your mapping, indeed twice. Can you post how you initialize the datastore? Especially how you
pass the epackages? Do you have subepackages?

Hi Thomas,
What is the dreamsPackage? And is one of the packages a subpackage of the other maybe?

Hi Thomas,
The only thing I can think of is that the eclasses actually occur twice in the list of eclasses for
which a mapping is generated. Can you set a break point in
HibernateMappingGenerator.processPersistentClasses and then check if you see the same EPackage and
EClasses passing by (same instance and same name/package)?
Then if you see this, backtrack along the stacktrace to see where the duplicates are coming from.

gr. Martin

The problem was in our initialization with the extended model. the
persistence was initialized before the emf was cleaned.

The most strange is in fact how it works with teneo 1.0.0 ???
