generating code while refering to a runtime instance of a model [message #431783]

Hello

I have a *.ecore file that refers to elements of a runtime instance of
an other model. If I try to create a genmodel for that there is no
referenced generator model to select at the last page of the wizard and
the root package of the referenced runtime instance of the model is not
shown either.
I already checked that the referenced model has the following extension
point declared:
<extension point="org.eclipse.emf.ecore.generated_package">
<package
uri = "http://www.eclipse.org/jcrm/0.8.0/dmodel"
class = "org.eclipse.emf.jcrm.dmodel.DmodelPackage"
genModel = "model/domainmodel.genmodel" />
</extension>

Any help is much appreciated.

Best,

Sandro

What do you mean with "runtime instance of another model"? Your
..ecore-file refers to model elements of another .ecore file?

You have to create a .genmodel file for your referenced model and add
this file on the last wizard page you mentioned.

Although extending the generated_package extension point is necessary
(or at least highly recommended) for model plugins, (as far as I know)
it has nothing to do with your cross model references issue.

When loading a resource to an ecore file one can choose between a
runtime instance and a development instance of a resource. In my case I
need a runtime instance. I learned that this runtime instance uses the
package URI (in my case http://www.eclipse.org/jcrm/0.8.0/dmodel) of the
model in the actual reference within the ecore file while the
development instance uses the file URI to the *.ecore file.
When I used the development instance there was no problem creating the
genmodel including references to an other model. But since I now need
the runtime instance it doesn't work anymore.

OK. I've tried to do the same and it worked for me - but "runtime
models" refers to all models that are registered in the currently
running platform (e.g. emf plugins and others), and not to models that
you have defined somewhere in your workspace (e.g. in your domain model
plug-in).
How did you manage to add a reference to your model? Did you modify the
ecore xml directly, or did you use the default ecore editor's "load
resource..." context menu and then choose "Browse registered packages"?

I used the "load resource..." action. In my case I have a generic model
in one Eclipse instance and start a second one. In this second instance
I create a new model refering to the runtime version of the generic model.
Thanks for having a look into it.

Best,

Sandro

Sandro,

You need to refer to the development time instance to generate code.
I'm not sure what else to say...

I just thought I can use a model containing a reference to a runtime
version of a model for both - generating code and working with it
reflectively as described in my post from last week.
But in this case I will just try to generate different ecore files with
MWE one with a development time reference and one with a runtime reference.
Thanks for your feedback Ed.

Cheers,

Sandro
