[acceleo 3.1] editor doesn't see inheritance [message #725703]

Hi,

I have a class called MetaModel located in b.ecore. it extends Artifact located in a.ecore.

The acceleo editor code assist suggests the attributes from MetaModel class but not from Artifact. If I type one of these manually, then the editor shows an error marker.

Any idea what could be the problem?

Here is how my template looks like:

[module genmodelGen('/plugina/model/a.ecore','/pluginb/model/b.ecore','http://www.eclipse.org/emf/2002/Ecore')/]
[template public genmodelGenComponent(c : MetaModel)]
    modelPluginID="[c.id/]" 
    modelName="[c.emfPackage/]" 
[/template]

c.id is not recognized and is part of Artifact class. c.emfPackage is recognized and is part of MetaModel.

Max

so I had to use oclAsType. Is there a way to avoid using this API?

Hi Maxime,

What you are trying to do should work.

I have tried to recreate the conditions of your environment and it worked for me as you can see it in this screenshot:

https://lh6.googleusercontent.com/-sx3rmeM1n2M/TndcSk7kWLI/AAAAAAAAAfA/IiOygrPTYnI/s600/metamodels.png

Does your project have a dependency with the two projects containing the metamodels? Are you using the binary serialization? (right click on your project -> properties -> acceleo), if yes, try XMI. Do you have the latest version of Acceleo 3.1.1? Could you try with it. I'll investigate more to see what could be the source of the problem.

Hello Stéphane,

I'm facing exactly the same problem on my project developped under Eclipse 3.5.2 with Acceleo 3.0.1.
In the editor's content assist, impossible to see the inherited attributes and references.
I don't know how to solve it ! I should use oclAsType() everywhere ! Project dependencies seem to be OK.

Regards,

Sébastien

Hi,

It is something that we improved for Acceleo 3.1.x so I'm not surprised if some problems appear in Acceleo 3.0.x

Sébastien,

As Stéphane mentionned, there have been a great deal of improvements in Acceleo 3.1 towards the resolution of metamodel dependencies in the modules. Do you have a particular reason for staying on the 3.0 stream? The 3.1 stream supports the same platforms as 3.0 did (all the way back to Eclipse 3.4 : http://wiki.eclipse.org/Acceleo/Compatibility). You can try installing it through the update site http://download.eclipse.org/modeling/m2t/acceleo/updates/releases/3.1 on any supported platform (http://wiki.eclipse.org/Acceleo/Installation).

If you do need to remain on the 3.0 stream, I cannot help more than Stephane did; you'll have to resort to "oclAsType" everywhere Acceleo does not manage to infer the type. Maybe try to import all needed metamodels in the module header, but if that does not help, then you're stuck with casting.

Hi Laurent and Stephane.

First, thanks for your replies.
No particular reasons for staying on the 3.0 stream. My main constraint is to use Eclipse 3.5.2 as target platform. When I installed my development platform, Acceleo 3.0.1 came with it ! Actually, I was not aware about the compliance between Acceleo 3.1.X and Eclipse 3.5.X. So, it's a great news for me !!!

Ok, update done to Acceleo 3.1.1. Behavior is better. My problem of cast is solved.
Thanks !

Sébastien
