Reference other Xtext model [message #1787252]

Hi guys,

I have two different Xtext models. Each with it's own DSL.
Now I want to make references from one model to the other one.
I already could "import" the other model i want to reference by:
- Add a import statement in Xtext model
- Add dependency in MANIFEST file
- Add theese two lines in workflow:

referencedResource = "platform:/resource/org.xtext.example.mydsl/model/generated/MyDsl.genmodel"
fragment = ecore2xtext.Ecore2XtextValueConverterServiceFragment2 auto-inject {}

No errors so far (however, is this the proper way to do?)

The problems occurs when debug the model.
Of course it does not find any elements to reference because it must read a file of the referenced model.
How to achieve that?

Thx for your help!

what do you mean by "must read" and "debug the model"

Problem solved.
I could not reference my other model because I did not used full qualified names.
But now another problems occurs to me:
I want to reference an element with an INT as name. Example :

Referenced model:

Model:  'ModelA' name=ID '{'
	(parts+=Part)* '}';
			
Part: 'ID' name=INT ;

Referencing model:

import ".../ModelA" as modelA

Model:
	imports+=Import*
	references+=[modelA::Part|FQN]
	;

Import:
	'IMPORT' importURI=STRING;

FQN:
	ID ('.' INT);

Everything works fine, if the type of Part's name is "ID". But if i use "INT" instead (like in the example above), the references are not resolved anymore.
What's the problem with replacing ID with INT?

you need to adapt the IQualifiedNameProvider (default is DefaultDeclarativeNAmeProvider) for your dsl see https://dietrich-it.de/xtext/2011/07/16/iqualifiednameproviders-in-xtext-2-0.html
