Because I would use "openWithSpec" to build only when the widget is ready, but it call a method (with the good pragma) on the class side. In the example i use i have add RadioButtonModel with addRadioButton: in the collection buttons, it's not empty but RadioButtonModel is a ComposableModel and layout: is define in the subclass DynamicComposableModel .

But why from the class side.
buttons ^ buttons
returns an empty collection
and
rebuildWidget self widgets removeAll. self createWidgets. self needFullRebuild: false. self buildWithSpecLayout: self dynamicLayout. self alignButtons

I was trying to use it but i have still the problem to call the instance method from the class side, so i call the buildWithSpecLayout: in the method to add buttons in the collection, it seems work but i have an "MessageNotUnderstood" RadioButton>>layout:

In fact i was trying to modify RadioButtonGroup to turn it into a widget, #buttons is not a widget but its collection of widget.
May you have confused RadioButtonGroup with the MenuModel / MenuGroupModel / MenuItemModel which are widgets. I take inspiration from them and I would got the same kind of behaviour.

Thanks Johan
We looked at
RadioButtonGroupExample
but you see we cannot have a RadioButtonGroupPresenter having 2, 3 or 4 radioButton.

Hi Marion,
the class side message of defaultSpec is generally meant to be used if you use a fixed number of widgets, so you can put the reference to the name of each widget there (in cour case #buttons). For variable number of widgets you should have a look at the dynamic features of Spec.
That being said, It looks like what you really want to use is a Radio Button Group. Have a look at RadioButtonGroupExample.

Hi, I'm trying to create a widget whith Spec, managing a collection of RadioButton. But I have a problem with defaultSpec (the accessor of the collection is the methods "buttons") :
If i put defaultSpec on class side, i can't acces the collection of the instance. (the following code iterate on the string)
defaultSpec <spec: #default> ^ SpecLayout composed newColumn: [ :column | #buttons do: [ :item | column add: item ] ]; yourself
If i put it on instance side, the lookup don't find it (in the book Building UI with Spec, it said the lookup begin by the instance side and it allow to have specific UI, in part about layout)
defaultSpec <spec: #default> ^ SpecLayout composed newColumn: [ :column | self buttons do: [ :item | column add: item ] ]; yourself
Any idea ?
