Comment #5 on issue 446 by tudor.gi...@gmail.com: uml class shape aligned the rectangles http://code.google.com/p/moose-technology/issues/detail?id=446
I tested some more and when we have only rectangle shapes, it seems to work just fine. So, the problem could be related to the ChildrenShape:
| builder | builder := MOFormsBuilder new. builder column; fill. builder row; fill; row; fill. builder x: 1 y: 1 add: (MORectangleShape new width: 30; fillColor: Color green). builder x: 1 y: 2 add: (MORectangleShape new height: [:x | x * 100] ). view shape: builder shape. view nodes: (1 to: 5)
