{

ISelection currentSelection = HandlerUtil.getCurrentSelection(event);
if (currentSelection instanceof IStructuredSelection) {
IStructuredSelection ss = (IStructuredSelection)currentSelection;
if (!ss.isEmpty()) {
Object so = ss.getFirstElement();

if (so instanceof EditPart) {
Object m = ((EditPart)so).getModel();
if (m instanceof EObject) {
EObject eo=(EObject)m;
DiagramImpl di=(DiagramImpl)eo;
Diagram d=di.basicGetDiagram();

Hi,

You can either create an EMF ResourceSet and a EMF Resource for your your file and use getContents()[0] on your resource file to get the top-level model element. Or you can use the OffscreenEditPartFactory to load your file with an offscreen GMF editor and then manipulate it with GMF APIs.

HTH,

IStructuredSelection ss = (IStructuredSelection)currentSelection;
if (!ss.isEmpty()) {
Object so = ss.getFirstElement();

if (so instanceof EditPart) {
Object m = ((EditPart)so).getModel();
if (m instanceof EObject) {
EObject eo=(EObject)m;
DiagramImpl di=(DiagramImpl)eo;
Diagram d=di.basicGetDiagram();
ResourceSet resourceSet = new ResourceSetImpl();
URI file=((EObject)m).eResource().getURI();
Resource modelResource=resourceSet.getResource(file, true);
List<EObject> ls=modelResource.getContents();
List<EObject> lm=ls.get(0).eContents();
NodeImpl ni=(NodeImpl) lm.get(0);
Node n=ni;
return (String) n.eGet(MistPackage.Literals.TEST_CASE__NAME);

}

}
}
}

Hi,

to get the root object of when having a EObject you can use EcoreUtil.getRootContainer(EObject);

Maybe this solves your problem.

Hi,

thank you very much! I used the "required Plugin identifiers" approach Smile

I did put code for this in my genmodel to generator model transformation.

Thanks!!

Object so = ss.getFirstElement();

if (so instanceof EditPart) {
Object m = ((EditPart)so).getModel();
if (m instanceof EObject) {
EObject eo=(EObject)m;
EObject root=EcoreUtil.getRootContainer(eo);
List<EObject> lot=root.eContents();
for(int i=0;i<lot.size();i++)
{
EObject temp=lot.get(i);
if (temp instanceof NodeImpl) {
NodeImpl node = (NodeImpl) temp;
EObject element = node.getElement();
System.out.println(element.toString());
if(element instanceof StartBlockImpl)
{
System.out.println("hurrai");
StartBlockImpl sb=(StartBlockImpl)element;
EObject tc=sb.eContainer();
if(tc instanceof TestCaseImpl)
{
TestCaseImpl tcl=(TestCaseImpl)tc;
return tcl.getName()+".mist";
}
}
}
}

}
