Get featureProvider from a given diagram

[Simone Di Cola]

Hi Joerg,

 Given an object of type Diagram, is it possible to get its relative feature provider? If yes, how? 

Thank for your time

Simone

Fix it.

just a pattern: Wait and you find out the solution yourself ;)

What do you mean with a pattern? Anyway I have another question. 

// Create the diagram

Diagram diagram = Graphiti.getPeCreateService().createDiagram(componentID, diagramName, true);

// Create the file

IFile diagramFile = diagramFolder.getFile(diagramName + "." + editorExtension); //$NON-NLS-1$

URI uri = URI.createPlatformResourceURI(diagramFile.getFullPath().toString(), true);

FileService.createEmfFileForDiagram(uri, diagram);

String providerId = GraphitiUi.getExtensionManager().getDiagramTypeProviderId(diagram.getDiagramTypeId());

DiagramEditorInput editorInput = new DiagramEditorInput(EcoreUtil.getURI(diagram), providerId);

IEditorPart openedEditor = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().openEditor(editorInput, editorID);

IDiagramContainer diagramContainer = (IDiagramContainer) openedEditor;

// Add the specified services

DiagramUtils.createServicesWithParameters(openedEditor,diagram, diagramContainer.getDiagramTypeProvider().getFeatureProvider(), compInst);

When I invoke DiagramUtils.createServicesWithParameters the transcation is always null. Why?

Mybe you have to execute it as RecordingCommand

[Simone Di Cola]

This is exactly what I do:

public static void createServicesWithParameters(IEditorPart ed,final Diagram diagram, final IFeatureProvider fp, final ComponentInstance compInstance) {
 TransactionalEditingDomain domain = TransactionUtil.getEditingDomain(diagram);
 domain.getCommandStack().execute(new RecordingCommand(domain) {
 @Override
 public void doExecute() {
 
 for (Service service : compInstance.getSelectedServices()) {

Then maybe try the approach from example 2 as presented here:
http://www.programcreek.com/java-api-examples/index.php?api=org.eclipse.emf.common.command.CommandStack

[Jörg Reichert]

here is another Graphiti API approach to get the editing domain:

DiagramEditorFactory.createResourceSetAndEditingDomain();

Thanks I've fix this. 

DiagramUtils.createServicesWithParameters(openedEditor,diagram, diagramContainer.getDiagramTypeProvider(.getFeatureProvider()), compInst);
