set XMI id of object during a QVTo transformation [message #1751073]

Hello everybody,
I would like to set xmi id to the objects created by my transformation (I will reuse when possible the id of my source model).
I know that QVTo doesn't work on XMIResource directly, but on ModelExtent, so it seems me not possible to do it during the transformation itself. Please someone can confirm me this point ?

I think I will create a map in a blackbox with the target objects and their ids during the transformation and apply them when the created objects are stored in the final XMI resource, but it seems dirty.

Do you have any opinion about this way ?

Regards,

HI Vincent

This is a FAQ for which I raised https://bugs.eclipse.org/bugs/show_bug.cgi?id=485439

xmi:id is not a model attribute, it is therefore invisible to modeling tools. Today, if you have a non-modeling requirement, you need to implement it in the non-modeling support. Probably in your XXXResource.save path.
