My EMF class has a feature of type EMap, I want to bind one of the
key-value pair to a swt Text control:

EStructuralFeature feature = xxxx;
IObservableMap observableMap =
EMFEditProperties.map(domain, feature).observe(info);

IObservableValue model =
Observables.observeMapEntry(observableMap,"key");
context.bindValue(SWTObservables.observeText(control, events), model);


But this does not work, when I type something in the Text control, the
value just cannot be set back to the map entry.

And I find out that in the EMFEditMapProperty class, the doSetMap method
like this:

protected void doSetMap(Object source, Map map, MapDiff diff)
{
EObject eObject = (EObject)source;
Command command = SetCommand.create(editingDomain, eObject,
getFeature(), map);
editingDomain.getCommandStack().execute(command);
}

it use a "SetCommand" to set the EMap feature, but this does not work.
And I find out that infact, EMap is not a java.util.Map, but is a
List... I think this could be a bug here, or I have mis-used this class?
