Hi,

Scenario:
I have a use case of reading from xmi to ecore model and then serializing it in xText model and then to a file.

Details:
Hence, i load emf model from xmi file.
There is attribute "public", type boolean in EClass "Attribute" which contains value "false" in the emf model.

Them xText grammer i have following rule:

Attribute returns Attribute:
	(public?='public')? 'Attribute' name=ID

I am serializing this model to xtext representation in the file via following code:

Injector injector = Guice.createInjector(new ControllerDslRuntimeModule());
XtextResourceSet set = injector.getInstance(XtextResourceSet.class);

XtextResource xtextResource = (XtextResource) set.getResource(targeturi, true);
xtextResource.getContents().add(controllerForXText);
try {
	// save it the new file
	Map<Object, Object> optionsMap = SaveOptions.defaultOptions().toOptionsMap();
		optionsMap.put(XtextResource.OPTION_ENCODING, "UTF-8");
		xtextResource.save(optionsMap);
	} catch (IOException e) {
		e.printStackTrace();
}

Since in the model the value of public was false i expected that in the dsl file keyword "public" should not appear.
But it is always there.

public Attribute attr1

What exactly what i am missing here ?
Any hint will be helpful.

Thanks and Regards,
Ashwani Kr Sharma

Hi sounds like a bug to me ( if the value really is false - did you
double check that)

Hi,

I checked content of xmi file using Sample Reflective Ecore Model. The editor shows the value is false.

I also debugged and checked the value in the model. There also the value is false.

Once i serialize and then load the model again from persisted dsl file the value is read as true.
I am using xText 2.4.0
Can i do something as quick win or workaround?

Regards,
Ashwani Kr Sharma
