[SOLVED] Failed to add a node in Activity diagram in a standalone application [message #891988]

Hello everybody,

I have created this simple model with one activity inside and I was trying to add the first node to the activity (the initial node)

Unfortunately there is now way I can get it done. The activity get correctly added to the model, but not the initial node

here is the code

	//Create the model
        Model model = UMLFactory.eINSTANCE.createModel();
        model.setName("Calico model");

        //Create the activity
        Activity activity_=UMLFactory.eINSTANCE.createActivity();
        model.createOwnedType("Activity", activity_.eClass());
        
        //Create the initial node
        InitialNode initialNode_=UMLFactory.eINSTANCE.createInitialNode();
        
        //add it to the activity
        //initialNode_.setActivity(activity_);
        
        //another try
        activity_.getNodes().add(initialNode_);
        
        //another try
        //initialNode_ = activity_.createNode("test",initialNode_.eClass());
        
        //save the model
        ResourceSet resourceSet = new ResourceSetImpl();
        UML300ResourcesUtil.init(resourceSet);
        Resource resource = resourceSet.createResource(URI.createFileURI("/home/motta/Desktop/Calico/CalicoSoft/AnalysisPlugin/model/model.uml"));
        resource.getContents().add(model);
        resource.save(null);

here are the libraries I am using

org.eclipse.emf.common_2.7.0.v20120127-1122.jar
org.eclipse.emf.ecore_2.7.0.v20120127-1122.jar
org.eclipse.emf.ecore.xmi_2.7.0.v20120127-1122.jar
org.eclipse.emf.mapping.ecore2xml_2.7.0.v20120130-0943.jar
org.eclipse.uml2.common_1.6.0.v201105021727.jar
org.eclipse.uml2.uml_3.2.100.v201108110105.jar

the xmi is attached. I am on Indingo
Thank you for your help

Update:

The problem should be when I save the XMI file.
In fact if I try to retrieve the Initial node it has been actually added to the internal structure of the activity

		for (Element descendant : activity_.allOwnedElements()) {
			if (descendant instanceof InitialNode){
				System.out.println("Found it");
			}
		}

Adding this snippet to the previous code actually I can find the initial node
However the node is missing in the xmi

solved! The problem was not correctly adding the activity to the model
here the corrected code

	//Create the model
        Model model = UMLFactory.eINSTANCE.createModel();
        model.setName("Calico model");

        //Create the activity
        Activity activity_=UMLFactory.eINSTANCE.createActivity();
wrong-->model.createOwnedType("Activity", activity_.eClass());
corr--->model.getPackagedElements().add(activity);
        
        //Create the initial node
        InitialNode initialNode_=UMLFactory.eINSTANCE.createInitialNode();
        
        //add it to the activity
        //initialNode_.setActivity(activity_);
        
        //another try
        activity_.getNodes().add(initialNode_);
        
        //another try
        //initialNode_ = activity_.createNode("test",initialNode_.eClass());
        
        //save the model
        ResourceSet resourceSet = new ResourceSetImpl();
        UML300ResourcesUtil.init(resourceSet);
        Resource resource = resourceSet.createResource(URI.createFileURI("/home/motta/Desktop/Calico/CalicoSoft/AnalysisPlugin/model/model.uml"));
        resource.getContents().add(model);
        resource.save(null);
