Hi,
In my dsl I have a cross reference between files and the references between files are sometimes not working. The Lazy linking doesn't return "sometimes" the objects on demand, therefore I have to explicitly resolve the proxy in scopeprovider. Is there another way to solve this problem?
List<Composite> composites = new ArrayList<Composite>();
if (context.getScreenType().eIsProxy()) {
EObject e = EcoreUtil2.resolve(context.getScreenType(), new ResourceSetImpl());
composites = EcoreUtil2.eAllOfType(e, Composite.class);
}
IScope result1 = MapBasedScope.createScope(IScope.NULLSCOPE, Scopes.scopedElementsFor(composites));
return result1;
And my dsl looks like:
Model:
(screenType=ScreenType | fbType=FbType);
ScreenType:
"screenType" name=ID
screen=Screen;
Screen:
"screen" name=STRING "{"
(rootComposite=Composite)?
"}";
Composite:
{Composite}
"composite" (name=ID)? "{"
composites+=Composite*
"}";
FbType:
(faceplateInstances+=FaceplateInstance)*;
FaceplateInstance:
"faceplateInstance" name=STRING "{"
"on screenType" screenType=[ScreenType|QualifiedName]
"in composite" composite=[Composite|QualifiedName]

Nope, it depends on build order, caches, units of work executed, lazy
linking, if you are looking at a possibly dirty resource (in the
editor), if the other resource is dirty, or not etc.
Use of index should be good for this kind of thing.
