Hi,
I have a metamodel M1 come from an external metamodel M2.
In M2 I have two classes M2C1 and M2C2. M2C1 contains 1...* M2C2.
In M1 I have two classes M1C3 and M1C4. MIC3 inherits from M2C2 and M1C4
contains 1...* M2C1 .
I don't want to implement the M2 metamodel because it's already
implemented in another bundle. When I create my genmodel on my M1.ecore,
M2 is defined as "Referenced generator models".
I generate the code from my genmodel.
When I create a new model with a M1C4 element as root element. M1C4
contains a child element M2C1. From the M2C1 element, I can create a M2C2
element but I can't create a M1C3 element which inherits M2C2 element.
Why ? How can I defined my genmodel to have the possibility to create the
M1C3 element from M2C1?
I hope I have been clear enough,
Best Regards,
Frédéric Barraillé

Thanks for your answer, it's corresponded to my problem.
My parent metamodel is UML, do you now if the UML code will generate with
the "Extensible Provider Factory" property sets to true in a futur version
?

Frédéric,
I know for a fact that UML has already been regenerated to be
extensible. Note that M5 has a bug in the child provider extenders
generation. :-( It's fixed in the latest integration build though.
The problem is that the plugin.xml registration for extenders is
generated only if you set child creation extenders to false, but of
course the class being registered is generated only if you set it to
true. So if you set to to false when generating the plugin.xml and
then change it to true to generate the class (the plugin.xml isn't
regenerated once it exists), then you'll be fine.
