Hi David,
The testcases use programmatic creation of the jdo file. Can you try the same using:
JpoxHelper.INSTANCE.generateMapping(...).

Hi,
So does this mean that no Teneo generated JPOX can be used unless you
programatically include the ECore package.jdo generation? I did not do
the library example, but had read the documentation but did not see this
requirement, which seems a fundamental one. Surely any pacakge.jdo
produced by Teneo will require use of the ECore classes and therefore
each time the ECore classes will be require enhancing too?
Thx.

Hi David,
No it is different. For featuremap (and anytype) Teneo has its own classes (for example
org.eclipse.emf.teneo.jpox.elist.AnyFeatureMapEntry). These are located in a separate jar file
(org.eclipse.emf.teneo.jpox.enhanced.jar) which is in the org.eclipse.emf.teneo.jpox plugin.
The classes in this jar file are already enhanced and the classes are exported by the
org.eclipse.emf.teneo.jpox plugin.
So in a plugin environment using the org.eclipse.emf.teneo.jpox will also make these enhanced
classes available to you. Enhancing the ecore classes is therefore not required.
It seems that during package.jdo generation the featuremap/mixed is not recognized as such.
Can you post the jdo you get? If you also post your model then I can reproduce it myself. You can
also send me the model directly (mtaal@elver.org).

Hi,
Another thing that confused me is the last item on the Troubleshooting
page. It says "Teneo uses the runtime version of the ecore model. The
runtime version is present as java code in the generated EPackage
implementation class." which made me think that that was how the ECore
classes got enhanced. But there is no sign of this EPackage generated file?
Thx.

Hi David,
Maybe the documentation is confusing in this regard.
To give some more background info. References to the Ecore model itself are not persisted as they
are statically present in the generated code. The only exceptions are featuremap (which supports the
mixed type) and anytype. Both of these require additional fields to store a reference to the ecore
model (to an efeature). However the ecore model is not persisted because the reference to the ecore
model is persisted as a string in the db. When the object (featuremap) is read back from the db then
the string is translated to the in-memory efeature. But this is only required for featuremap.

Hi David,
No it is different. For featuremap (and anytype) Teneo has its own classes (for example
org.eclipse.emf.teneo.jpox.elist.AnyFeatureMapEntry). These are located in a separate jar file
(org.eclipse.emf.teneo.jpox.enhanced.jar) which is in the org.eclipse.emf.teneo.jpox plugin.
The classes in this jar file are already enhanced and the classes are exported by the
org.eclipse.emf.teneo.jpox plugin.
So in a plugin environment using the org.eclipse.emf.teneo.jpox will also make these enhanced
classes available to you. Enhancing the ecore classes is therefore not required.
It seems that during package.jdo generation the featuremap/mixed is not recognized as such.
Can you post the jdo you get? If you also post your model then I can reproduce it myself. You can
also send me the model directly (mtaal@elver.org).

Hi,
Another thing that confused me is the last item on the Troubleshooting
page. It says "Teneo uses the runtime version of the ecore model. The
runtime version is present as java code in the generated EPackage
implementation class." which made me think that that was how the ECore
classes got enhanced. But there is no sign of this EPackage generated file?
Thx.

Hi David,
Maybe the documentation is confusing in this regard.
To give some more background info. References to the Ecore model itself are not persisted as they
are statically present in the generated code. The only exceptions are featuremap (which supports the
mixed type) and anytype. Both of these require additional fields to store a reference to the ecore
model (to an efeature). However the ecore model is not persisted because the reference to the ecore
model is persisted as a string in the db. When the object (featuremap) is read back from the db then
the string is translated to the in-memory efeature. But this is only required for featuremap.
