Dear all,
I have defined a DSL (gorgiasdsl) and generated the xtext artifacts. I can load a model and manipulate it using EMF. However, when it comes to saving the model I get a "ValueConverterWithValueException: String literal is not properly closed" error.
What can be the problem?
I attach my code and the StackTrace:
//load model fro dsl
Injector injector = new GorgiasDslStandaloneSetup().createInjectorAndDoEMFRegistration();
XtextResourceSet resourceSet = injector.getInstance(XtextResourceSet.class);
resourceSet.addLoadOption(XtextResource.OPTION_RESOLVE_ALL, Boolean.TRUE);
Resource resource = resourceSet.getResource(URI.createURI("file:///C:\\kb.gorgiasdsl"), true);
GorgiasProgram model = (GorgiasProgram) resource.getContents().get(0);
//model is correct
//save model
try {
HashMap saveOptions = new HashMap();
saveOptions.put(XtextResource.OPTION_ENCODING, "UTF8");
resource.save(new FileOutputStream("myapplication.gorgiasdsl"), saveOptions); } catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

Hi,
please set a breakpoint in
ValueSerializer.serializeAssignedValue(EObject, RuleCall, Object, INode,
Acceptor) and try to figure out what's wrong with the node.
Except from that, I think there is a missing try-catch in the framework
code. Could you please file a ticket?
To workaround that one, you may want to specialize the ValueSerializer
and override the questionable method.
Regards,
Sebastian
