types. I mean I don't want to create them in my metamodel but rather
want to use them in my generated editor as references. In the ecore
diagram editor I tried to load resources... but I only can load ecore
models in the workspace or filesystem and not in the registry. Is it
possible anyhow?

Ok so it works. If you add a reference in the sample editor first you
can work with the imported package in the ecore diagram editor as well.
But now I have another problem. In my genmodel the imported package
appears as well - understandable. The generation of the editor worked
fine except an error in one test class. For now I commented the line out
where a not existent method is to be invoked. But in the new eclipse
instance, where I want to work with my editor, I get the following error
when starting the creation wizard:
Plug-in "myplugin.editor" was unable to instantiate class
"myplugin.presentation.ModelWizard".
Could not initialize class myplugin.MyModelPackage
that's caused by the following line in the init method of my package impl:
TypePackageImpl theTypePackage =
(TypePackageImpl)(EPackage.Registry.INSTANCE.getEPackage(Typ ePackage.eNS_URI)
instanceof TypePackageImpl ?
EPackage.Registry.INSTANCE.getEPackage(TypePackage.eNS_URI) :
TypePackage.eINSTANCE);
and by the following line in my imported TypePackageImpl:
XMLTypePackage theXMLTypePackage =
(XMLTypePackage)EPackage.Registry.INSTANCE.getEPackage(XMLTy pePackage.eNS_URI);
What can I do to avoid this?

Gilbert,
How exactly do those lines cause a problem? The XMLTypePackage does
exist. When you created your GenModel, did you choose the existing
GenModel for XMLTypePackage in the final wizard or create a new
GenPackage for it?

In my genmodel appeared a new package for the XMLTypePackage
automatically when adding references to it in my metamodel. How can I
specify to choose an existing genmodel and where do I find it?

Ok, it works in that way if you delete the genmodel and generate it
again. But you can't reference the other genmodel if your own genmodel
already exists - or I didn't find it.
But I think my explanation from my first post was a little bit
underinformed (nice word ;) ). I try to explain in other words what I
want to do:
I start from behind. With the generated editor I want to create a model
for my domain. In this domain I need datatypes as well. My idea was that
it would be nice if one can reference existing XML simple datatypes such
as xs:string for example. Or one has the option to create special types
and reference those. That's why I thought that I can create a class
(AbstractDatatype) in my metamodel inheriting from a root class of the
XMLTypes package. I thought there is a class from which all simple xml
types inherit, which I can use as parent class for my AbstractDatatype.
Furthermore my idea was that now I simply can reference the parent class
of all simple XML types in my metamodel. I thought that by that I can
then reference all XML simple types or an own special type (inheriting
from the parent XML simple type). That means I don't want to use the
metaelements from the XMLTypes package and the concrete types in my
generated editor or alternatively some special types. Is it
udnerstandable? And the more important question: is it possible?
best regards,
Gilbert

I have another idea. Maybe the following scenario is possible:
in the second Eclipse instance where the generated editor is available:
- create a new XML schema
- create an instance of my metamodel with the generated editor
- in that instance load the created xml schema as resource
- in that instance reference a type contained in the xml schema
Is that possible or is it to freaky?

existing genmodel? If I load a resource in the ecore file I can add
references to the loaded model. But by that my genmodel won't contain a
reference to the genmodel from which the model was loaded. I have real
packages. How do I do this when my genmodel already exists? How do I
reference a genmodel from the emf registry?

This is right - but the wizard can only be used when I want to create a
new genmodel. My genmodel exists already so I can't use it :/
