hi
i am a newer of xtext . and do not know how to use referenec in xtext file. i had upload my ecore file(a pic) , in ecore file Connection -> iNodeConnection it is include two reference (source and target), how to define it in xtext file?
this is a fragment of my xtext file :

grammar org.talend.metalanguage.jobscript.JobScript with org.eclipse.xtext.common.Terminals

import "platform:/resource/.../model/xmlmap.ecore" as xmlmapFile

XmlMapData returns xmlmapFile::XmlMapData:
{xmlmapFile::XmlMapData}
'addXMLMapData'
'{'
('addInputTree' '{' inputTrees += XMLInputTree'}')*
('addOutputTree' '{' outputTrees+=XMLOutputTree'}')*
('addVarTable' '{' varTables+=XMLVarTable '}')*
('addConnections' '{' connections+= XMLConnection'}')*
'}'
;

XMLConnection returns xmlmapFile::Connection:
{xmlmapFile::Connection}
('addSourceNode' '{' source= [xmlmapFile::AbstractNode]'}')?
('addTargetNode' '{' target= [xmlmapFile::AbstractNode]'}')?
;

seems the red code not correct.

hi
thank you for your reply . my problem is how to manage correctly the references
. We found few help on internet, and with this, we wrote partially this script above.
Is there some example (script + definition + code sample) somewhere ?"
by the way we use actually "only" the version 1.0.1 of xtext.
