What is the intention of invoking serialization when calling XtextResource.save()? [message #762553]

When I rename the file test.mydsl, the serialization will be used. However, if there are some syntax errors in that file, the serialization will fail. And, the content of that file will loss. I think it is an error that the textual content of a file loss because of renaming it.

Why does not xtext keep the textual content unchanged when XtextResource.save() is called?

Can I use the parer tree serialization instead of the AST serialization?

Hi Kevin,

the textual form is potentially out of sync with the object model. The
purpose of #save is to persist information that can be restored to an
equal instance by means of #load afterwards. It would be pointless to
persist the outdated version, wouldn't it?

Regards,
Sebastian
