Adding diagram to EMF models

Question

I am writing an ATL translation from BPMN2 to another model. The target model editor requires a GMF diagram to open the output of ATL transformation. In the following rule, I create the diagram the problem is that the diagram and the model are not written in the same file. If I choose the same file for their output one overrides the other.

rule def2mod {
    from
        b: BPMN20!Definitions
    to
        m: reo!Module,
        m : GMF!Diagram(
            type<-'Reo',
            name<-'test',
            measurementUnit<-#Pixel
        )   
}

I have posted the atl code and my input here at: https://github.com/behnaaz/BPMN2ATL.git

Merging the content of these file in one file is also not helping. The output are generated as: File 1:

<?xml version="1.0" encoding="ISO-8859-1"?>
<notation:Diagram xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:notation="http://www.eclipse.org/gmf/runtime/1.0.2/notation" xmi:id="_zHQiAB6HEeaECbYRnMkrCw" type="Reo" name="test" measurementUnit="Pixel"/>

File 2:

Something that works so far is to open the emf model in java code runtime and add the diagram programmatically as:

//module is my emf model generated by ATL
Diagram diagram = ViewService.createDiagram(module, ModuleEditPart.MODEL_ID,
    ReoDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
res.getContents().add(diagram);
res.getContents().add(diagram.getElement());
res.save(module, Collections.EMPTY_MAP);
