Should I call my EMF generated validators myself in standalone mode? [message #1405114]

Hi,

I'm implementing an xtext standalone application. I get to load my model (the code is in scala), but the EValidator errors do not appear when I do getErrors on the resource.

Should I call my EMF generated validators myself in standalone mode or will it be done automatically?

        val injector = (new TransitionSystemDslStandaloneSetup()).createInjectorAndDoEMFRegistration();
        val resourceSet: XtextResourceSet = injector.getInstance(classOf[XtextResourceSet]);
        resourceSet.addLoadOption(XtextResource.OPTION_RESOLVE_ALL, true);
        val uri = config.model.toURI().toString()
        val resource = resourceSet.getResource(URI.createURI(uri), true);
        logger.trace(s"Starting to load model from url: $uri")
        val ts = resource.getContents().get(0).asInstanceOf[TransitionSystem];

Hi

yes, you need to call it yourself, e.g.,

// validate the resource
List<Issue> issues = validator.validate(resource, CheckMode.ALL,
CancelIndicator.NullImpl);
if (!issues.isEmpty()) {
for (Issue issue : issues) {
System.err.println(issue);
}
}

hope this helps
Lorenzo
