Problem with the root of a metamodel instance, again.

The problem was that the properties Child, Create Child and Notify of the
root model references were false instead of true.
Right now I'm working with a different model, but I have the same problem
that those days. However, now I have checked the properties and the
containment, and they have the true value.
Here I attach a piece of the model. The root is the DTD class.
I don't know if the proble is due to the abstract class nature of the
referenced Element.
The .ecore model has been implemented with the topcased ecore editor, and
all the stuff has been automatically generated.
Thanks in advance,
Toņi

Toņi, If hitting finish seems to do nothing, probably there's an error being logged in the Error log view that will provide a clue.

I've created that appears in the error log view. I hope this can help to detect

Re: Problem with the root of a metamodel instance, again.
Toņi, It sounds like a resource implementation was created that doesn't even support save. I have a hard time imagining how that would be the case since all resource implementations except ResourceImpl itself do implement doSave. Look closely as the extension you're using and what resource factory is registered for that extension.

Toņi, What does DTDResourceImpl extend? You didn't set the GenPackage's Resource Type property to "Basic" did you? That would be my guess. I assume you'd actually want XMI or XML, otherwise you'll need to implement your own save and load support. Toņi Reina Quintero wrote: > How can I checked the extension you have mentioned?

Eclipse Ganymede and the modelling plugins, and in this case the tree editor
works perfectly. So, maybe this can be a mistake detected in an earlier version
of EMF. The version that comes with ganymede is EMF 2.4.0, while the version I
have installed in my "old Eclipse Europa" is EMF 2.3.0. Do you know any bug
related to this problem?
Re: Problem with the root of a metamodel instance, again.
Toņi, The newer EMF might well create registrations in the plugin.xml that don't work with older versions. Use the debugger to see what kind of resource implementation is being created in the wizard...
