Hi all,

I've decided to perform some tests with the EEF framework with the aim
of enriching our UI support for the CDO framework. Lot of interesting
features in this new exciting project, so kudos to all the folks that
make it possible :)

I've been following the instructions provided at:

http://wiki.eclipse.org/EEF_tutorial_:_First_generation

with the following environment:

Eclipse Helios 3.6 M4: I20091210-1301
EMF 2.6.0.v200912121603
Acceleo SDK 0.9.0.v200912150944
EEF 0.8.0.v201001040921-177-7w312112151A32 (fetched from the nightly
builds update site)

So far I've just created the .components and .eefgen models through the
"Initialize EEF models" action. Then, I took a quick look at the models
(no modifications) and generated. I didn't get any error message or
such, and the code wasn't generated. I found this exception in the error
log:

The model I'm using is org.eclipse.emf.cdo.tests.model1 and can be found
at
dev.eclipse.org:/cvsroot/modeling/org.eclipse.emf/org.eclips e.emf.cdo/tests/org.eclipse.emf.cdo.tests.model1

Hope the information provided is enough. Don't hesitate asking for
further information / tests :)

Cheers,
Víctor.

Hi again,

I would like to add that the generator also returns the same exception
with a simple model that I've made for testing purpose (1 EClass with 2
EAttributes, EString and EInt).

Cheers,
Víctor.

Hi Victor,

First thanks for the kudos ;) It's not the first time we encounter this
problem, We'll see this problem with Acceleo Team today.

Hi Goulwen,

thanks for the assistance. Shall I open a bug to keep track of it?

Cheers,
Víctor.
