Using the attached project from this thread I am trying to get the properties view be filled with the properties of the current selection in the diagram but I am somehow unable to get it working. Tried to implement IPropertySource within the domain model objects but that doesn't seem to be enough. Any idea what I am missing here / what is required to get the properties view filled with the properties of the currently selected figure in the diagram?
thanks in advance,
Lars

Hi ,
I use the example in this post as reference for creating Graphiti diagrams.The latest code that is posted on this thread works for me in version 0.9.1 perfectly.
I have recently migrated my code from version 0.8.2 to 0.9.1 with which my code does not seem to work.I am doing nothing different apart from replacing the code with appropriate API of 0.9.1.
I use the following code in my Action class to open the editor:
IWorkbenchPage page = PlatformUI.getWorkbench()
.getActiveWorkbenchWindow().getActivePage();
final IEditorInput editorInput = RepositoryUtils.getEditorInput();
final DiagramTypeProvider dtyProvider = (DiagramTypeProvider)
ExtensionManager.getSingleton().createDiagramTypeProvider(
DIAGRAM_TYPE_PROVIDER_ID);
final Diagram diagram = Graphiti.getPeCreateService()
.createDiagram(DIAGRAM_TYPE, "Test Diagram",
false);
final TestDiagramEditor diagramEditor = new TestDiagramEditor();
dtyProvider.init(diagram, diagramEditor);
page.openEditor(editorInput,TestDiagramEditor.DIAGRAM_EDITOR_ID);
And the code for getEditorInput() of RepositoryUtils is as follows:
public static IEditorInput getEditorInput() throws Exception {
private final static String DIAGRAM_NAME = "NonEmf.diagramNonEmf";
String diagramFileName = "";
String dataFileName = "";
final IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
IPath path = root.getLocation();
dataFileName = path + "/files/NonEmf.xml";
diagramFileName = path + "/files/NonEmf.diagramNonEmf";
final IProject project = root.getProject("files");
if (!project.exists()) {
project.create(null);
}
if (!(project.isOpen())) {
project.open(null);
}
IFile diagramFile = project.getFile(DIAGRAM_NAME);
URI emfURI = URI.createURI(diagramFile.toString());
TestDiagramEditorInput result = null;
if (emfURI != null) {
URI diagramUri = emfURI.appendFragment("/0");
result = new TestDiagramEditorInput(diagramUri, null);
result.setDataFileName(dataFileName);
result.setDiagramFileName(diagramFileName);
}
return result;
}
}
The same thing used to work for me for version 0.8.2. Now I do not get any error but the diagram file is not created and when I open the editor since there is no diagram file under the given path following message is shown on editor :"No Diagram found for URI 'L/files/NonEmf.diagramNonEmf#/0"

Hi Hemlata,
I am happy that my example has helped you.
In fact, the code from the example should be migrated to Graphiti version 0.9.x.
In the Github version of my example (https://github.com/kumarunster/phirea.public/tree/master/test.graphiti.nonemf) you can see the current state of the example, and it runs on 0.9 version of Graphiti, but unfortunately I cannot exactly say (on the fly), what you should change...
In the whole example I'm trying to show, how is it possible to use Graphiti based editors without EMF lock-in of the domain model. If you look at ApplicationWorkbenchWindowAdvisor you have a Tip, how to get the right EditorInput for your Graphiti-Editor.
About my case: In my application I have a datamodel, that is stored in a database and a lot of graphiti-xml-files, that are stored in a database too. The graphiti-xml's are all created programatically from some template-files, and all the referenced objects in that diagram files are drag-n-dropped from my "Repository". That files are copied, if a EditorInput is produced, in a Temp-Folder from my Application every time the new User-Session is started and a diagram is requested. On Save-Actions they are stored in the DB as BLOB.
If you have any questions, so feel free to ask me and look to the github version of my example!
Best regards,
Nikolai

Hi Nikolai,
Thanks for that valuable info.
I use the github version of your example which works well with Graphiti 0.9.1 as well.
I do get EditorInput for my Graphiti-Editor the way you get it in ApplicationWorkbenchWindowAdvisor.
In my case I do not want to persist graphiti related info in the database.Right now I am just trying to add the pictogram representation of the domain object to the diagram editor with version 0.9.1
I try to create my own Graphiti diagram as follows:
IWorkbenchPage page = PlatformUI.getWorkbench()
.getActiveWorkbenchWindow().getActivePage();
IEditorInput input = RepositoryUtils.getEditorInput();
// Create the pictogram for selected Functional Variable
final Diagram diagram = Graphiti.getPeCreateService()
.createDiagram(DIAGRAM_TYPE, sourceVariable_.getName(),
false);
DiagramEditor editor = new DiagramEditor();
final DiagramTypeProvider dtyProvider = (DiagramTypeProvider) ExtensionManager
.getSingleton().createDiagramTypeProvider(
DIAGRAM_TYPE_PROVIDER_ID);
dtyProvider.init(diagram, editor);
page.openEditor(input, DiagramEditor.DIAGRAM_EDITOR_ID);
With this blank graphical editor opens up.And now I try to add the buisness object to this diaram using following stuff:
AddContext addContext = new AddContext();
addContext.setNewObject(object);
addContext.setLocation(200, 300);
addContext.setSize(100, 200);
addContext.setTargetContainer(diagram);
DiagramFeatureProvider fp = (DiagramFeatureProvider) dtyProvider
.getFeatureProvider();
AddFunctionalVariableFeature feature = (AddFunctionalVariableFeature)
dtyProvider.getFeatureProvider().getAddFeature(addContext);
dtyProvider.getFeatureProvider().addIfPossible(addContext);
When using this ,internally it gives Nullpointer exception for getEditDomain() in addIfPossible method as follows:
org.eclipse.core.runtime.AssertionFailedException: null argument:
at org.eclipse.core.runtime.Assert.isNotNull(Assert.java:85)
at org.eclipse.core.runtime.Assert.isNotNull(Assert.java:73)
at org.eclipse.graphiti.ui.editor.DiagramEditor.executeFeature(DiagramEditor.java:1946)
at org.eclipse.graphiti.features.impl.AbstractFeatureProvider.addIfPossible(AbstractFeatureProvider.java:331)
I suppose that is because my editor is not getting initialised properly.
On debugging I see that my Editor has no TransactionalEditingDomain.With version 0.8.2 I created my own TransactionalEditingDomain and passed that to constructor of DiagramEditor. But in version 0.9 there is no constructor which accepts TransactionalEditingDomain.
I am now stuck at point as how to add the pictogram on the diagram with the new version of Graphiti.
