Hello,
When you add a component to a scroll pane, using the mouse and pointing on a parent scroll pane in the hierarchical bean view, the viewport is not automatically updated. You have to set manually the viewport view.
This is quite confusing, especailly when comparing with other GUI builders.
I would suggest the viewport view property of a scroll pane being automatically initialized when a component is added to a scrollpane.
Cheers,
Fred
