Hi Usman,

In your example, I would expect to have the layout applied on the two groups. Each group should therefore stay grouped. There is a bug, indeed. But I do not see how your version of Roassal2 solves the situation. I have found and fixed the problem. I think it will also work for you. 

Update Roassal and try the following:
-=-=-=-=-=-=-=-=-=-=-=-=
view := RTView new.

es1 := (RTEllipse new color: Color lightRed; size: 20) elementsOn: (1 to: 20).
RTForceBasedLayout on: es1.
view addAll: es1.

es2 := (RTEllipse new color: Color lightGreen; size: 20) elementsOn: (1 to: 20).
RTForceBasedLayout on: es2.
view addAll: es2.

es3 := (RTEllipse new color: Color lightBlue; size: 20) elementsOn: (1 to: 20).
RTForceBasedLayout on: es3.
view addAll: es3.

RTForceBasedLayout new 
charge: -800;
on: (Array with: es1 with: es2 with: es3).
view open
-=-=-=-=-=-=-=-=-=-=-=-=

It will produce the following:

Hi,

We spotted a bug related to edge driven layouts and groups. So, when a view has groups in it, performing an edge driven layout gives MNU: RTGroup>>view.

The bug can be reproduced with the following script in latest Roassal. 

view := RTView new.
group1 := RTGroup new add: (RTBox new elementOn: 1); yourself.
group2 := RTGroup new add: (RTEllipse new elementOn: 2); yourself.
view addAll: group1; addAll: group2.
RTForceBasedLayout on: (RTGroup with: group1 with: group2).
view open

The link to get the version with changes (because problem posting more than 1 mb on this list):

All tests are green after the change.

Alex, can you integrate this in Roassal because it is important for our work.

tx,

Usman & Leo
