HUTN generated no model [message #15582]

Hi all,
the Epsilon HUTN implementation writes no model.
I get no error!
I get the following message
Generated /home/......../workspace/hutn/TROPIC/tropic.model
But there is no "tropic.model" at that location.
I donwloaded eclipse from
http://www.eclipse.org/gmt/epsilon/download.php
yesterday.
I installed the stable version of epsilon first and then,
after I got no model, the interim version of
epsilon.
Can anybode help me or give me a hint, whats the problem could be?

thx,
mse07004

Hi,

Could you please attach the .hutn and the respective .ecore so that we
can try to reproduce this?

Cheers,
Dimitris

The Ecore File, as emfatic:

@namespace(uri="families", prefix="families")
package families;

abstract class NamedElement {
attr String name;
}

class Family extends NamedElement {
attr String[*] address;
ref Pet[*] pets;
attr int numberOfChildren;
val Person[*] members;
attr String ~id;
attr boolean nuclear;
attr float averageAge;
readonly derived ref Dog[+] dogs;
ref District#families district;
}

class Pet extends NamedElement {
attr boolean male;
}

class Person extends NamedElement {
}

class Dog extends Pet {
attr boolean loud;
attr DogBreed[1] breed;
ref District#dogs district;
}

enum DogBreed {
poodle = 1;
labrador = 2;
}

class District {
val Family[+]#district families;
val Dog[+]#district dogs;
}

class Model {
val NamedElement[*] contents;
val NamedElement[*] contents2;
}

The HUTN File
@Spec {
metamodel "families" {
nsUri: "families"
}
}

families {
Family "F" {
id: "F"
numberOfChildren: 1
nuclear: false
averageAge: 20.5
members: Person "father", Person "mother", Person "child"
pets: Pet "dog"
}

Person "father" {
name: "father"
}

Person "mother" {
name: "mother"
}

Person "child" {
name: "child"
}

Dog "dog" {
male: true
loud: false
breed: labrador
}
}

Hi,

I can't seem to be able to reproduce the problem... In my machine saving
the .hutn file produces a .model file as expected. Perhaps Louis (CC'ed)
can help more with this.

Cheers,
Dimitris

Hi,

I've been able to recreate the problem. This seems to be caused by
either a change in the interface to, or a regression of, Epsilon's EMF
model support.

mse07004, could you open a bug on the Epsilon bugzilla to track this? I
will work on a patch:

https://bugs.eclipse.org/bugs/enter_bug.cgi?product=GMT& component=Epsilon

Cheers,
Louis.

Thanks very much. We're still working on a patch; we think it may be a
regression in Epsilon's model connectivity layer.

Cheers,
Louis.

Hi,

It should be fixed now. Could you please update from the interim site
and confirm this?

Cheers,
