Hi,

Is it allready possible that WindowBuilder makes his bindings as EMFEditObservables. This way I can connect to a EditingDomain. Hope someone can help me.?

Regards

Hi,

I would strongly advice against using EMFEditObservables which is going
to be deprecated (I hope with the upcoming release).

All *new* features are added to the EMF(Edit)Properties-API. I know
WindowBuilder does not support the properties stuff I only wanted to
speak out that this is legacy API and though we'll probably won't break
you by removing it's not in our main focus.

So what would you recommend we should do? Manually add all the bindings using EMF (edit) properties?

Well because I'm not using GUI-Builders I have no suggestion I can only
tell you which API we are supporting for the future.

The best would be if someone would implement Properties-Support in
WindowBuilder but I think it's not very high on their list (just doing
guess work here) but you should ask at their forum.

Ok, thanks for your reply. I will use EMFEditProperties.

I'm having trouble transforming my tableviewer from EMFObservables to EMFProperties. Below you see my old and new code, but the new code doesn't display any data. The second one (in comment) however displays everything correctly..

		IObservableSet set = listContentProvider.getKnownElements();

		IObservableMap[] map = new IObservableMap [2];
		map[0] = EMFProperties.value(ModelPackage.Literals.PERSON__ID).observeDetail(set);
		map[1] = EMFProperties.value(ModelPackage.Literals.PERSON__NAME).observeDetail(set);

		tableViewer.setLabelProvider(new ObservableMapLabelProvider(map));

		IEMFListProperty personsProp = EMFProperties.list(ModelPackage.Literals.PERSONS__PERSONS);
		tableViewer.setInput(personsProp.observe(persons));

//		IObservableList personsPersonObserveList = EMFObservables.observeList(persons, Literals.PERSONS__PERSONS);
//		tableViewer.setInput(personsPersonObserveList);

What value is stored in "persons"? Can you give me a bigger context?

Persons holds a collection of multiple Person objects (feature Literals.PERSONS__PERSONS). When I print out both observablelists, they both hold these objects. But one displays them in the tableviewer and the other one doesn't.

So you say:

Collection persons = ...

This would be wrong. Please show me where you populate the "persons"
variable.

They are stored in a database.

We have 2 objects in our EMF model:

- Persons (Holds a collection of Person objects)
- Person (name etc)

There is only one Persons object, so we do it like this: Resource.getContents(0), from this object we call the feature. That isn't wrong, right?

So how are you reading them, I guess you are using Teneo? If that is the
case you'll have to set an IElementComparer because Teneo lists violate
the default list contract.

See http://www.eclipse.org/forums/index.php/mv/msg/136745/431468/
unfortunately the referenced thread there does not work any more.
