Before I switched to the latest Teneo build, I used the following annotation
on my ID attributes to set the generator in the hibernate mapping:
<eAnnotations source="http://hibernate.elver.org/GeneratedValue">
<details key="strategy" value="AUTO"/>
</eAnnotations>
In the latest build, I don't get the <generator> element in the hibenate
mapping anymore.
Any suggestions as for what I'm doing wrong?

Hi Martin,
Thanks. I changed the annotation to the following and it work as expected:
<eAnnotations source="teneo.jpa/Id">
<details key="appinfo" value="@GeneratedValue(strategy="AUTO")"/ >
</eAnnotations>
However if I attach this annotation to an EDataType and use this for the id
attributes in all of my classes, this only work for the first class in the
package. For example, if I have two classes Foo, Bar in my package, both
with an id attribute of EDataType ID, where ID is annotated as shown above.
Then when I create the hibernate mapping, only class Foo gets the <generator
class="native"/> element.
Switching the order of the classes in the package to Bar, Foo results in
only class Bar having the <generator class="native"/> element instead.
I decided to dig into this issue and found the following:
The GeneratedValue attribute is contained in the HbAnnotatedEDataType Class,
as are the other annotation attributes.
Therefore the first call to "pea.eSet(asf, ped.eGet(esf));" in the
PersistenceMappingBuilder removes the value from the HbAnnotatedEDataType
instance, preventing it from being copied the next time.
I suggest the following fix:
replace "pea.eSet(asf, ped.eGet(esf));" with "pea.eSet(asf,
EcoreUtil.copy(ped.eGet(esf)));"

Thanks GertJan for researching the cause of this.
I committed a solution similar to your proposal.
