problems with global scoping [message #1699239]

I have created a xtext project with the eclipse wizard.

grammar org.xtext.example.mydsl.MyDsl with org.eclipse.xtext.xbase.annotations.XbaseWithAnnotations

generate myDsl "http://www.xtext.org/example/mydsl/MyDsl"

Model:
	'package' name = QualifiedName
	(imports = XImportSection)?
	content +=Content*
;	
	
Content:
	TypeDef|TypeRef
;
TypeDef:
	'def' name=ValidID type=JvmTypeReference 'length' length=INT
;

TypeRef:
	'ref' name=ValidID ('extends' superType=[TypeRef|QualifiedName])? 
	types += TypeRefValDef*
;

TypeRefValDef:
	'val' name=ValidID type=[TypeDef|QualifiedName]
;

Now running the dsl as eclipse project adding the following to files:

package test

def def1 String length 10

ref Ref1 
val d def1

package test

ref Ref extends test.Ref1

In the last I get the message Couldn't resolve reference to TypeRef 'test.Ref1'.

I read lots about GlobalScopeProvider, XtextResourceDescriptionStrategy, ... etc., and I think I start to understand the big picture,
I have the strange feeling, that the ResourceDecriptions (Index) is not build correctly.
When I try to read allResourceDescriptions from the ResourceDescriptionsProvider I get an empty List.

I have no idea what I am missing.

Hi,

your example works fine. did you do any customizations so far?!?
if you use the open model element dialog, can you see the elements.
is your model project a java project or not.
if it is: are the models in a source folder?

Thanks for the answer
I downloaded a new luna with the xtext 2.8.3 installed (just to be sure) and created a new xtext-project as described.

1.) no I did not do any customization
2.) If you mean the Outline dialog. Yes I can see all the elements in the tree.
3.) Yes my model project is a Java Project
4.) Yes the models are in the src folder in the test package. (To make sure I create a Java-class in that package and it worked like expected)

The message is only shown in the editor window, but not in the tree of the Package Explorer.

Any other clue? Where can I start debugging?

Ok the Open Model Element Dialog is empty.

What may be the reason?
