Hi Guys.

Problem:
With the generated EMF-Editor, i can create new cars (see mymodel) but cant access them with Xtext. I tried to combine 2 Xtext Projects with each other and this works fine.

1.I have a EMF Project with a Ecorefile "mymodel":
(Carports contains Cars)

<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="mymodel"
nsURI="http://mymodel/" nsPrefix="mymodel">
<eClassifiers xsi:type="ecore:EClass" name="Carport">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="name" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
<eStructuralFeatures xsi:type="ecore:EReference" name="cars" upperBound="-1"
eType="#//Car" containment="true"/>
</eClassifiers>
<eClassifiers xsi:type="ecore:EClass" name="Car">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="name" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
<eStructuralFeatures xsi:type="ecore:EReference" name="drivers" upperBound="-2"
eType="#//Driver" containment="true"/>
</eClassifiers>

2.Than i made a new Xtext Projekt:

import "platform:/resource/org.emf.test.mymodel/model/mymodel.ecore " as mymodel

Model:
cars+=Car*;

Car:
'mycar' name=[mymodel::Car];

3.The referenced GenModel is part of the MWE2-File

I couldnt find a description in the doc.
If there is one, please give me a hint.

Thanks for your help.

Hi,

you have to build an infrastructure to add the .mymodel files yourself. (Writing a ResourceServiceProvider)

have a look what xtext does for .ecore files in the plugins org.eclipse.xtext.ecore and org.eclipse.xtext.ui.ecore and Adreas Graf described in his blog for .uml files http://5ise.quanxinquanyi.de/2010/10/31/xtext-1-0-0-and-uml- xpand-on-top/
