removing group nodes in Roassal2

Hi!

Wrong usage of RTGroup :-)

You need to have "view addAll: group.” and _not_ “view add: group”
Maybe you want to add a signalUpdate in the callback.

Your script should be:
-=-=-=-=-=-=-=-=-=-=-=-=
| view |

view := RTView new.
menuBuilder := RTMenuBuilder new view: view.
menuBuilder menu: 'Click Me' background: Color gray callback: [
                view clean.

                view signalUpdate

].
group := RTGroup new.
(1 to: 10) do: [:each| group add: ((RTBox new borderColor: (Color green); elementOn:each)
                @ RTDraggable;
                +(RTLabel new color: (Color red);
                text: each asString; yourself))].

view addAll: group.

RTVerticalLineLayout on: view elements.
view open.

-=-=-=-=-=-=-=-=-=-=-=-=

Cheers,
Alexandre
