[news.eclipse.modeling.gmf] Re: EMF / GMF : sharing Editing Domain

[charles.souillard@xxxxxxxxxxxxxx (Charles SOUILLARD)]

Hi,

I tried your solution. I still have an error :
While executing the operation, an exception occurred
Caused by: java.lang.NullPointerException
	at 
org.eclipse.emf.workspace.AbstractEMFOperation.inheritedOptions(AbstractEMFOperation.java:240)
	at 
org.eclipse.emf.workspace.AbstractEMFOperation.execute(AbstractEMFOperation.java:149)
	at 
org.eclipse.core.commands.operations.DefaultOperationHistory.execute(DefaultOperationHistory.java:511)
	... 50 more

The problem I have is that when I try to get my editing domain (from 
refresh method or inside My Operation), it returns to me null.

Do I have something special to do to register my editing domain ?

here is the code I added : 
public void refresh() {
   	TransactionalEditingDomain.Registry registry = 
TransactionalEditingDomain.Registry.INSTANCE;
   	final TransactionalEditingDomain txDomain = 
registry.getEditingDomain("org.bonitasoft.studio.diagram.EditingDomain");
   	try {
			OperationHistoryFactory.getOperationHistory().execute(new 
MyOperation(txDomain, "mylabel", this), null, null);
		} catch (ExecutionException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
   }
   
   private static class MyOperation extends AbstractEMFOperation {
   	private NameSection nameSection;
		public MyOperation(TransactionalEditingDomain domain, String label, 
NameSection nameSection) {
			super(TransactionalEditingDomain.Registry.INSTANCE.getEditingDomain("org.bonitasoft.studio.diagram.EditingDomain"), 
label);
			this.nameSection = nameSection;
		}
		@Override
		protected IStatus doExecute(IProgressMonitor monitor, IAdaptable info)
				throws ExecutionException {
			this.nameSection.element.setName(this.nameSection.getText().getText());
			return null;
		}
   }
Thanks
