cross reference between two resources [message #1820807]

Hi all,

I am using Autosar model in my xtext grammar.
My use case is I will have arxml file with some configuration, for one element in the arxml file i need to open xtext editor.
My problem here is element has cross reference to another element, which will be present in autosar resource not in xtext resource.
How i will show that element in content assist.

Any help would be much appreciated!

Thanks!!

for autosar (i assume you use artop) you have to come up with a manual scoping solution

Hi,

Thanks for the quick replay.

I tried to implement the same way as it is there in this link - https://blogs.itemis.com/en/combining-emf-models-with-xtext-dsls.

I am getting error "Couldn't resolve reference to Node 'Root'".

I have attatched the files.
can any one please tell where i am doing wrong.

Thanks!!

Hi,

could you create a branch with the name forum/thread1102196 on the https://github.com/itemis/xtext-issues GitHub repository and upload your project there?
Please also update your TestProject.

Hi,

I have another problem now. The same thing i did for AUTOSAR model, In content assist element to be referred is being shown as proxy object.
Why element is becoming proxy, how i can resolve.

Xtext grammar-

// automatically generated by Xtext
grammar org.xtext.example.xtext.MyDsl with org.eclipse.xtext.common.Terminals

import "http://www.eclipse.org/emf/2002/Ecore" as ecore
import "platform:/resource/org.artop.aal.autosar446/model/autosar446.ecore#//swcomponent/composition"

CompositionSwComponentType:
{CompositionSwComponentType}
'CompositionSwComponentType{'
('ShortName:' shortName=String0)?
('DataTypeMappings:'dataTypeMappings+=[DataTypeMappingSet|String0] (','dataTypeMappings+=[DataTypeMappingSet|String0])*)?
(checksum=String0)?

where is your autosarnameprovider. autosar stuff has no "name" afaik but hierarchical IDS.
also where does the metamodel come from you are using?
if you use artop the approach wont work
you have to use sphinx to load the models and
put it into scope manually

see Scopes.scopeFor methods. simply pass your object and nameprovider there
