[Acceleo] Dynamic model support appears broken [message #654983]

I submitted this as an Acceleo bug but have seen no activity on it, so I'm cross-posting the issue here in case it's user error:

I'm using Acceleo SDK 3.0.1.v201009150438. I want to use dynamic models but it
appears that this feature is broken.

1. Create an empty acceleo project
2. Create a simple ecore file with one top level class named AcceleoBug.
3. Create a new mtl generator file, select the newly created ecore file.

Note that the line in the template file that reads:
[file (a.name, false, 'UTF-8')]

has an error (unrecognized variable: "name")

Is this a bug or is there something else I have to do to make Acceleo aware of the Ecore meta-meta-class's name field?

Hi,

Stephane:

Thanks for the quick answer! To clarify, I was talking about using dynamic instances as described in section 7.3 of this tutorial.

Your mtl file should look like this (not using the Ecore meta-model, but your custom one.)

Quote:

[module generate('/org.eclipse.acceleo.test/model/My.ecore')/]
[template public generate(e : AcceleoBug)]
...

The purpose of doing all of this is to speed development by avoiding the necessity to spawn children Eclipse sessions and to avoiding splitting the whole project into two parts (metamodel and model/generated source.)

Stephane:

I was wondering if you had a chance to reproduce the problem when using the custom meta-model (as opposed to using the standard ecore model.)

Thanks,
Jeff

To update anyone else interested in this: According to Laurent Goubet, this is currently a known bug/limitation in Acceleo.
