Re: How to build a model programmatically ?

Hi,
thanks for resending the e-mail - it was necessary (at least for me :)) 
- I did miss it.
The problem seems to be that one of the references (or association ends, 
or associations) in your metamodel is not public. All model elements 
need to be public. Otherwise the behavior is undefined and may cause 
exceptions like this.
Regards,
Martin
