Hi,
My previous question did not get any answer 
So I decided to rephrase the question:
Imagine the internal ECore model associated to a DSL is modified independently from any manual entry from the Xtext file Editor generatied for my DSL (for instance by loading a model from outside of the editor). How is it possible to transform this model into text so that it can be read and modified from the Xtext file editor ?
Thanks.

Rountrip engineering is considered harmful, as usually you have a higher
level of abstraction on the DSL side, and it is not generally possible
to map things from the target back.
If you want to go this direction nevertheless, you should maybe
transform your model to a DOM and serializing this instead of using a
code generator. That transformation is likely to be much easier to
reverse. But you have been warned.
