Hi,

i am not sure in which context you want to do this (standalone/from eclipse)
you may have a look at http://wiki.eclipse.org/Xtext/FAQ#How_do_I_load_my_model_in_a_standalone_Java_application.C2.A0.3F

my whole code is ; (just creating SitePermission but this element dont shown in deneme.user file)


ResourceSet rs = new ResourceSetImpl();
		SitePermission sitePermission= null;

Resource resource = rs.getResource(
					URI.createURI(userFile.toURI().toString()), true);

UserModel eobject = (UserModel) resource.getContents().get(0);

UserPackage.eINSTANCE.eClass();
		// Retrieve the default factory singleton
		UserFactory factory = UserFactory.eINSTANCE;
		// SitePermission
		SitePermission sitePermission = factory.createSitePermission();
		sitePermission.setName(name);
                //Other changes
userModel.getSitePermissions().add(sitePermission);

HashMap saveOptions = new HashMap();
		    saveOptions.put(XtextResource.OPTION_FORMAT, Boolean.TRUE);
		    try {
				resource.save(new FileOutputStream("deneme.user"), saveOptions);
			} catch (FileNotFoundException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			} catch (IOException e) {

Hi,

i use 2 project one is User xtext Project, second is my content GMF project on GMF project when web created (on CreateWebCommand) above code triggered and on User file SitePermission element added. and Web element reference to it. (i have 2 file one is content another is user)

when i do this
i have got this error

Save Failed
No EObjectDescription could be found in Scope Web.sitePermission for UserModel.sitePermissions[0]->SitePermission'Serhat'
Semantic Object: ContentModel'CM'.ownedWeb->Web'fsdg'

Do you have any idea why the reference and element cannot be found on file please ?

i dont know much both 2 project are different. And each project have different metamodel and xtext gramer but content grammer imports user grammer because on web element its have referance to users sitePermission element

(content project synchronized with its GMF project)

Hi,

are you in eclipse? or standalone?

standalone both have to be in the same resourceset.

HI,

i mean: how do you execute the code? java main?
are the metamodels different. if so do you provider a resourceserviceprovider for the gmf stuff?

Hi

I have user project and its grammer is;


UserModel returns UserModel:
	('sitePermissions' '{' sitePermissions+=SitePermission (sitePermissions+=SitePermission)* '}' )?
;

SitePermission returns SitePermission:
	'sitePermission' name = QualifiedName '{'
		'webGUID' '=' webGUID=STRING
	'}'
;

and I have content project and its grammer is;

ContentModel returns ContentModel:
	'ContentModel'
	name=QualifiedName
	'{'
		'webApplicaitonName' '=' webApplicataionName = STRING
		'siteCollectionName' '=' siteCollectionName = STRING
		('description' '=' description=STRING)?
		ownedWeb=Web
	'}';

Web returns Web:
	'Web'
	name=QualifiedName
	'{'
                 'sitePermission' '=' sitePermission = [user::SitePermission|QualifiedName]
		('Webs' '{' ownedWeb+=Web (ownedWeb+=Web)* '}' )?
	'}';

I can create 2 project well and they work greate. (i follow http://christiandietrich.wordpress.com/2012/08/07/xtext-referencing-elements-of-one-dsl-from-another-dsl/)

But i just want to on contents Diagram project (XText and GMF project shares Contents EMF classes (ex ContentPackage, ContentFactory ..)) when Web created i must add a SitePermission element to created.user file

and i must do this on content xtext project too when web created i must add SitePermission to created.user file too

can i explain more ?

Regards

HI,

if you have dsl for both you want to reference from one dsla file to another dslb file?
then simply make sure that both are in the same container
(resourceset standalone, iproject in eclipse)

yes they are on same container but when dsla creates web element dslb must create SitePermission element and web element must referance this SitePermission on its attribute

automaticly
