Hi,

I tried to generate diagram nodes and link programatically using EMF command and it worked fine, except node locations

I tired to relocated node using SetBoundsCommand 

GraphicalEditPart gEditpart = (GraphicalEditPart)editpart;
Rectangle rect = gEditpart.getFigure().getClientArea().getCopy();
rect.setLocation(location.x, location.y);
SetBoundsCommand sbc = new SetBoundsCommand(editpart.getEditingDomain(), "change location", new EObjectAdapter((View) editpart.getModel()), rect);

editpart.getDiagramEditDomain().getDiagramCommandStack().execute(new ICommandProxy(sbc));


after executing above command, it looked fine as expected

but when reopening diagram in the editor, I am getting this error

IRJS0007E Semantic refresh failed

Hi Melan,

what causes the NullPointerException in your CanonicalEditPolicy? (TestDiagramCanonicalEditPolicy.java:201)
Which element is null?

Hi,

Thanks for the quick reply, getSource() and getTarget() of DiagramLink getting null, I am not familiar with this code

EObject diagramLinkSrc = nextDiagramLink.getSource().getElement();
			EObject diagramLinkDst = nextDiagramLink.getTarget().getElement();



refreshConnections() of CanonicalEditPolicy as below 

/**
	 * @generated
	 */
	private Collection<IAdaptable> refreshConnections() {
		Map<EObject, View> domain2NotationMap = new HashMap<EObject, View>();
		Collection<EsbLinkDescriptor> linkDescriptors = collectAllLinks(
				getDiagram(), domain2NotationMap);
		Collection existingLinks = new LinkedList(getDiagram().getEdges());
		for (Iterator linksIterator = existingLinks.iterator(); linksIterator
				.hasNext();) {
			Edge nextDiagramLink = (Edge) linksIterator.next();
			int diagramLinkVisualID = EsbVisualIDRegistry
					.getVisualID(nextDiagramLink);
			if (diagramLinkVisualID == -1) {
				if (nextDiagramLink.getSource() != null
						&& nextDiagramLink.getTarget() != null) {
					linksIterator.remove();
				}
				continue;
			}
			EObject diagramLinkObject = nextDiagramLink.getElement();
			EObject diagramLinkSrc = nextDiagramLink.getSource().getElement();
			EObject diagramLinkDst = nextDiagramLink.getTarget().getElement();
			for (Iterator<EsbLinkDescriptor> linkDescriptorsIterator = linkDescriptors
					.iterator(); linkDescriptorsIterator.hasNext();) {
				EsbLinkDescriptor nextLinkDescriptor = linkDescriptorsIterator
						.next();
				if (diagramLinkObject == nextLinkDescriptor.getModelElement()
						&& diagramLinkSrc == nextLinkDescriptor.getSource()
						&& diagramLinkDst == nextLinkDescriptor
								.getDestination()
						&& diagramLinkVisualID == nextLinkDescriptor
								.getVisualID()) {
					linksIterator.remove();
					linkDescriptorsIterator.remove();
					break;
				}
			}
		}
		deleteViews(existingLinks.iterator());
		return createConnections(linkDescriptors, domain2NotationMap);
	}


Thanks,
Melan

Hi,
this is strange. Are you sure that setting the bounds causes the edge to loose the source and the target?
If you can upload the project, I will have a look at it.
Regards,

Andreas

Hi,

Yes, I was wrong. I noticed it just did not happen when setting the bounds. I was able to get rid of it by calling my code async way via ProgressMonitorDialog, I don't understand why this is working!

my code as follows

try {
			Shell activeShell = PlatformUI.getWorkbench().getDisplay().getActiveShell();
			ProgressMonitorDialog progressMonitorDialog = new ProgressMonitorDialog(activeShell);
			progressMonitorDialog.setOpenOnRun(true);
			progressMonitorDialog.run(true, false, new IRunnableWithProgress() {

				@Override
				public void run(IProgressMonitor monitor) throws InvocationTargetException,
						InterruptedException {
					try {
						monitor.setTaskName("Generating diagram from source");
						Deserializer.getInstance().updateDesign(xml, graphicalEditor);
						setSourceDirty(false);
					} catch (Exception e) {
						new InvocationTargetException(e);
					}
				}
			
			});
			
		} catch (InvocationTargetException e) {
			log.error("Error while generating diagram from source",e.getTargetException());
		} catch (InterruptedException e) {
			log.warn("The operation was canceled by the user", e);
		} finally{
			firePropertyChange(PROP_DIRTY);
		}


Thanks,
Melan
