Hi,

I try to migrate may work with the last version of gmf.
In my case I use an extension genmodel to add particularities in the code
generation.

To do the extension for gen model, I create an ecore file, and I add a
reference to the GenCommon base. Then
I generate the genModel, but I obtain the following warning:
"The generic type associated to the 'EJavaClass' Classifier shoudl have 1
type argument(s) to match the number of type parameter(s) of the
classifier".

And if I continue I cannot fo reference to It in my custom template.

I downloaded the plugin codegen, and I don't succed to validate the viewmap
element of the gmfgen.ecore
This is the same mistake as before.

Hello Patrick,

There is a validation problem in gmfgen.ecore, but even with this problem
it is possible to successfully generate working code from there, so the reason
is not in a validation of .ecore file i think.

Yes, indeed I have succeed to generate the genmodel and generated code.

I try to modify a template. The completion by taking in account the model
extension runs but when I generate code, I obtain the following error for
the element of my model extension:
org.eclipse.gmf.internal.xpand.model.EvaluationException: Unrecognized
variable:

Hello Patrick,

Do you know exactly wich variable was not recognized?
Onfortunately there is no debug support for xpand in GMF, so you have to
debug templates by tracing/modifying it..

The variable that is not recognized is the meta element.

I have tried this test in the template:

Hello Patrick,

> //ExtendedeGenNode.allInstances()->size()
> ExtendedeGenNode is a element of my model gmfgenextension.
> The error is the variable ExtendedeGenNode is not recognised.
Can you try something like:
<<gmfgenextension::ExtendedeGenNode.allInstances()->size()> >?
BTW, in do you have any compilation errors from xpand? It should highlight
this place.

Hello Patrick,

Can you please tell me more about your problem? Do you have code generated
for this model? Are you executing one more instance of Eclipse having gmfgenextension
model registered in package registry or you are working with EMF dynamic
instances loaded from .ecore file located nearby?

> There is a mistake :" couldn't find operation 'allInstances' for EClass"
Original error message was a bit different did you change anything to get
this message? Is is a compilation-time error or runtime one?

I've tried to use allinstacnes in my custom templates for the custom model
type loaded dynamically from .ecore file located nearby and it works ok..

Hi Alex,
now it runs, but I don't know why.
To respond to your question:
-I have done a ecore model for the extension gmfgen. I have generated
the code and the model is registered withe the extensionpoint generated
package.
- I also done a feature and a updatesite. I install this plugin in my
environment.
- then I use the procedure to add an extension model on the gen model.
- In template file I refer registered metamodel and work on it.

now it runs. I remark that if I write the paclage of the metamodel in the
template, I have no the completion.

I wonder if there is cache to clean that it explain why my template run now.

Hello Patrick,

So, if you have this plugin installed then corresponding meta-model should
be available in EMF package registry, so there should be no problems with
finding it.

We have a number of problems with code completion in xpand editor, so I know
it. ;-)

Nothing except model registry. In case you have somewhere in workspace checked
out verion of .ecore genmodel extension model then it can be loaded by xpand
and incorrectly mized with one from EMF package registry, otherwise I can
not see any reasons for this problem.
