The attribute "xyz" is not transient so it must have a data type that is serializable?!? [message #512813]

I defined an attribute as EMap<?,?> at which point I got the subject error
message. But also after changing the two arguments to EString (i.e. the type
now reads EMap<EString, EString>) I keep getting that error message. I would
argue, that String ARE serializable. Or are EStrings not?

Michael,

If you defined a map like, this it will be serialized automatically:

2.29 How do I create a Map in EMF?
< http://wiki.eclipse.org/index.php/EMF/FAQ#How_do_I_create_a_ Map_in_EMF.3F>

But if you define an EDataType, then you're responsible for how to
serialize an instance of that as a whole.

I tried to create a map according to the referenced description, but even
though the validation finds not problem and the definition even seems to
make sense (at least to me) the generated code does not even compile...

I attach the .ecore and .genmodel files. Any ideas?
