Hi,
I was trying to serialize my model using a resource that i get by using this injector:

Injector injector = new MDSLStandaloneSetup().createInjectorAndDoEMFRegistration();

bu i got this error Quote:

java.lang.IllegalStateException: Passed org.eclipse.xtext.builder.clustering.CurrentDescriptions not of type org.eclipse.xtext.resource.impl.ResourceSetBasedResourceDescriptions

So i found latter that i must use this injector instead

Injector injector = Guice.createInjector(new MDSLRuntimeModule())

The problem that i have by using this is that the top node of my resource is now
Quote:

MMC.impl.PackagesImpl@1ec16bfb (name: racine)

instead of Quote:

org.eclipse.emf.ecore.impl.DynamicEObjectImpl@51103d14 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@5c33a5f5 (name: Packages) (instanceClassName: null) (abstract: false, interface: false))

Is there a way to get back the dynamicEobject by using the guice injector?

Thanks in advance

new MDSLStandaloneSetup().createInjectorAndDoEMFRegistration(); should dio the very same.
sure you dont have any strange customizations there?

Yes im sure

                Injector injector = Guice.createInjector(new M2CDSLRuntimeModule());
	       //Injector injector = new M2CDSLStandaloneSetup().createInjectorAndDoEMFRegistration();
		XtextResourceSet resourceSet = injector.getInstance(XtextResourceSet.class);
		resourceSet.addLoadOption(XtextResource.OPTION_RESOLVE_ALL, Boolean.TRUE);
		 resource = resourceSet.getResource(
		//URI.createURI("platform:/resource/POCModel_v2/model/rr.m2c"), true);
		URI.createURI("platform:/resource/"+racine+"/"+fileName), true);
		 EcoreUtil.resolveAll(resource);
		modelRoot =  resource.getContents().get(0);

My modelRoot is different depending only on what injector i use. Isnt there an alternative solution like for exemple to convert the packageImpl to dynamicEObject

Here is what xxxdslStandalonesetup does:

	public Injector createInjectorAndDoEMFRegistration() {
		org.eclipse.xtext.common.TerminalsStandaloneSetup.doSetup();

		Injector injector = createInjector();
		register(injector);
		return injector;
	}
	
	public Injector createInjector() {
		return Guice.createInjector(new org.xtext.example.mydsl.MyDslRuntimeModule());
	}

there is no difference

are you sure you did not touch xxxdslStandalonesetup???

and what is the difference in the model????
and where do you call the code.

can you share a grammar + a unit test reproducing the problem?

Thinks Christian, i'm glad I did not do something stupid. So i think that i will just keep using the createInjectorAndDoEMFRegistration(). In this case is there a way to solve the first issue related resource serialization

[Worker-3] ERROR org.eclipse.xtext.buil der.impl.XtextBuilder  - Passed org.eclipse.xtext.builder.clustering.CurrentDescriptions is not based on a resource set
java.lang.IllegalStateException: Passed org.eclipse.xtext.builder.clustering.CurrentDescriptions is not based on a resource set

May i ask another question plz. Sometimes i got this error even if in my grammar the gathersC has 0..* multiplicity

org.eclipse.xtext.validation.IConcreteSyntaxValidator$InvalidConcreteSyntaxException: These errors need to be fixed before the model can be serialized.
Packages: Feature Packages.name must be set.
Packages: Feature Packages.gathersC holds 0 non-transient value(s), but at least 1 are required.

Hi,

sorry i have no idea what you are actually doing in your code. XtextBuilder is for IDE so i wonder it is mentioned in an environment where you use standalonesetup which should never never never ever be used in eclipse

I solved the problem. In fact you previous question is the hint. I had two projects one with the xtext nature and another without. In the runtime i was calling the resource by using methods from first projects and apply the save in the second project. I merged the two projects and the problem appears to be solved. Thanks chritian
