Hi,

I use the latest 2018-09 Eclipse/EMF version. I found something strange while I was modelling an array of generics. Let's say I want to model the following method:

public Binding[] bindValues(DataBindingContext context, IObservableValue<?> targetObservableValue, IObservableValue[] modelObservableValues, UpdateValueStrategy<?, ?> modelToTarget)

In XCore I modeled it that way.

...
type DataBindingContext wraps DataBindingContext
type ObservableValue wraps IObservableValue<?>[]
type UpdateValueStrategy wraps UpdateValueStrategy<?, ?>
type Bindings wraps Binding[]  

type ObservableValues wraps IObservableValue[]  // XCore raise a WARNING!!!

op Bindings bindValues(DataBindingContext context, ObservableValue targetObservableValue, ObservableValues modelObservableValues, UpdateValueStrategy modelToTarget) 
..

This generate the method as expected.

However, If I fix the XCore warning that way.

type ObservableValues wraps IObservableValue<?>[]  // No warning.

Here is the way the method is generated.

public Binding[] bindValues(DataBindingContext context, IObservableValue<?> targetObservableValue, IObservableValue<?> modelObservableValues, UpdateValueStrategy<?, ?> modelToTarget) {

Is it normal?

Have a nice day.

Regent ;-)
