[news.eclipse.modeling.gmf] Re: create and display copy of existing EObj

["Felix Förster" <heggly@xxxxxxx>]

Hi Jevon,

the diagram updates when I press F5. Saving the diagram adds the new 
operator to the XMI file. However, all containment references are not 
included, i.e. atomic operators are contained inside the complex 
operator. Those are neither contained in the XMI file nor in the 
diagram when I double click on the complex operator.
I tried to manually put the changes in the resource:

Resource importResource = op.eResource();
Resource thisResource = 
editPart.getEditingDomain().getResourceSet().getResources().get(0);
thisResource.getContents().addAll(EcoreUtil.copyAll(importResource.getContents()));

This gives an IllegalStateException. Is it possible to create a 
SetCommand to modify a resource? The usual way doesnt work since 
Resource is not an EObject and I can't a reference to the 
EStructuralFeature "contents". Is there any other way to solve this?

Thanks for your answer.
Felix.
