Use EObjectValidator in UpdateValueStrategy [message #896979]

I am trying to connect the validation methods I've defined in an EObjectValidator to an AggregationValidationStatus so that it can produce validation messages in the UI.

So far, I've got the following code when I create the binding:-

binding = bindingCtxt.bindValue(uiObs, modelObs, new EMFUpdateValueStrategy().setAfterConvertValidator(new IValidator() {
			
			@Override
			public IStatus validate(Object value) {
				/* WHAT DO I NEED TO PUT IN HERE? */
			}
		}), null);

So the question is, how do I make my EObjectValidator do the validation work for me to get the relevant messages from the model validation in the UI?

Thanks in advance.

Simon,

Diagnostician.INSTANCE can be used to validate an instance.
BasicDiagnostic has static methods like toIStatus for converting a
Diagnostic to an IStatus.
