[news.eclipse.tools.emf] Re: Referencing model elements (generated edito

[Michael Gebhart <lists@xxxxxxxxxxxx>]

Hi,

thanks for you help. Very interesting. When I use a containment reference 
everything is working. But if I don't set containment to true I doesn't. 
In the properties view the reference is listed, but I can't select the 
element.

If I generate an editor for the second model it is working.

Any idea how I can make it working with a reference and no containment?

Greetings

Mike
