Description Csaba Koncz

2013-07-18 17:19:53 EDT

Invoking "Initialize Ecore Diagram file..." from the context menu on an Xcore file with very simple content throws exception.

Intstallation: 
Eclipse Standard/SDK
Version: Kepler Release
Build id: 20130614-0229

EMF - Eclipse Modeling Framework SDK 2.9.0.v20130610-0406
EMF - Eclipse Modeling Framework Xcore SDK 1.1.0.v20130612-0809
Diagram Editor for Ecore (SDK) 1.2.0.201306071421

No other feature was installed.
The content of the test Xcore file was this:

<code>
package m

class A{
  String name
}
</code>

(If I remove the attribute "name", the diagram is created.)

Please find the exception stack trace below.

Responding to the thread "Ecore Tools and Xcore Problem and Synchronization" in emft:

I am using the latest modeling download form eclipse.org and only added Xcore and Xtext.

These are the projects that I use and I am trying to create a diagram for 'rtt.xcore'

[robotics/rodinia.git] / source / be.kuleuven.rodinia.model.rtt /
[robotics/rodinia.git] / source / be.kuleuven.rodinia.dsl.rtt /

Comment 4 Csaba Koncz

Hugo,
I do not think this change is available on the official update sites yet.
What you need to do is to get the EMF code and compile the org.eclipse.emf.codegen.ecore plugin on your own. 
You might then create a feature patch for feature org.eclipse.emf.codegen.ecore (this is what I did) and install it in the IDE you use to do your Xcore development.
Or is there maybe an update site for nightly builds or interim releases?

Comment 5 Ed Merks

The fix is available in the 2.9.1 service release or a 2.10 milestone build.
