Hi,
I have two models (Model1,Model2)in my ETL code. When I use the copy operation of the 'org.eclipse.epsilon.emc.emf.tools.EmfTool' tool, which model is selected for target of the copy operation? My code is :

var temp:= Model2.createInstance(Model1.type().name);
	var emfTool : new Native("org.eclipse.epsilon.emc.emf.tools.EmfTool");
	var n := emfTool.getECoreUtil().copy(temp);

After running the this code, is temp copied to Model1 or model2? How can I manage it?

Best Regards.

Hi Mahsa,

At this point the clone does not belong to either model. To add it to a model you'll need to either add it to the contents of the resource that underpins it (e.g. Model1.resource.contents.add(n)), or add it to a containment reference of a model element that already belongs to that model. Please note that if you're cloning elements you'll need to disable the "Cache..." option in the model configuration dialog.

Cheers,
Dimitris
