I am able to show the decorators on the node use a service method that returns an image when the diagram opens. This service method is written to give different images based on a criteria.
My question is how to make the diagram to reload the decorator when the respective semantic model's attribute has changed that in turn has need to update the decorator. If the service method is invoked again it will now return a different image.
The problem is the service is not looked up again. I had put a break point which comes during start-up but not later.
So far I have tried the following which have NOT worked for me -
1. Refresh the parent
StructuredSelection strSelection = (StructuredSelection) selection;
Object firstElement = strSelection.getFirstElement();
if (firstElement instanceof DNodeEditPart) {
DNodeEditPart dNodeImpl = (DNodeEditPart) firstElement;
dNodeImpl.getParent().refresh();
}
2. Refresh the representation
StructuredSelection strSelection = (StructuredSelection) selection;
Object firstElement = strSelection.getFirstElement();
if (firstElement instanceof DNodeEditPart) {
DNodeEditPart dNodeImpl = (DNodeEditPart) firstElement;
TransactionalEditingDomain domain = TransactionUtil.getEditingDomain(dNodeImpl.getEditingDomain());
EditPart parent = dNodeImpl.getParent();
if (parent instanceof IDDiagramEditPart) {
IDDiagramEditPart dPart = (IDDiagramEditPart) parent;
RefreshRepresentationsCommand command = new RefreshRepresentationsCommand(
domain, new NullProgressMonitor(), dPart.resolveDDiagram().get());
domain.getCommandStack().execute(command);
}
}
Item 2 was due to https://www.eclipse.org/forums/index.php/t/657840/

Hello
If the code called when you make a change from the property section does not modify the resource of the Sirius ResourceSet then nothing will be triggered by sirius. It will be up to your custom code to force a refresh.
In addtion, I did not understand if your 2. Refresh the representation point did work or no at the end. IMO it should refresh properly
