Feature xyz must be set [message #776752]

Hi,

I'm running in a problem when using ETL, I don't know where it origins, maybe someone of you has a hint?
Im executing a standalone ETL transformation. I'm trying to save my target model, I've set:

emfModelTarget.setStoredOnDisposal(true);

When I invoke the module via

module.execute();
module.getContext().getModelRepository().dispose();

it crashes with:

org.eclipse.xtext.validation.IConcreteSyntaxValidator$InvalidConcreteSyntaxException: These errors need to be fixed before the model can be serialized.
Model: Feature Model.document must be set.

(why in org.eclipse.xtext.validation? where does this come from?).
So I don't know why that happens because in my .etl I'm pretty sure I'm setting this feature:

rule Model2Model
transform m : Source!Model
to m : Target!Model {
	("Transforming a Model to a Model").println();	
	var neet := new Target!NonEmptyElementTag;
	var stag := new Target!STag;
	stag.name := "span";
	neet.stag := stag;
	var etag := new Target!ETag;
	etag.name := "span";
	neet.etag := etag;
	m.document = neet;
}

Any guesses? What could be the problem?
Best regards
Yves

Hi Yves,

At a first glance, both the input and the output parameters of your transformation rule appear to be named "m". Could you perhaps try changing this and giving it another go? If this still fails, please put together a minimal configuration that we can use to reproduce this and send it to us at epsilon.devs gmail com.

Hi,
thanks for the quick reply.
I had no success renaming the target model to a unique name, still the same exception.
Attached my minimal example, somehow with this setup the target model is empty.
You can see my standalone setup here: pastebin.com/kW3wv8sB
Is there anything else I can try?
Best regards
Yves

Now this problem is solved, I had to set the source model to

emfModelSource.setStoredOnDisposal(false);

Now a new exception is kicking in:

java.lang.RuntimeException: The context 'Model' is not valid for type 'Model'

Is it correct for Xtext to serialize the model? The transformation is working in a different standalone setup. Any ideas what could be wrong?

I accidentally named the output model with an extension of ".html" instead of ".xmi", this made Xtext treat it and serialize it. Case closed. Thanks for the help.
