TransitionComposite - SWT Exception when child is disposed

[GoogleCodeExporter]

I want to dynamically create and remove some contents of the 
TransitionComposite.
If i dispose a child of the composite, it generate a SWT Exception : Widget is 
disposed.
This is due to the fact that the computeSize method uses the private attribute 
'controls' and compute the size of each element of this list regardless their 
disposed state.

The change below resolve the problem :

public void addControl(final Control control) {
        checkWidget();
        if(!control.isDisposed()) {
            this.controls.add(control);
            if (this.controls.size() == 1) {
                control.setVisible(true);
            } else {
                control.setVisible(false);
            }

            control.addListener(SWT.Dispose, new Listener() {
                @Override
                public void handleEvent(Event event) {
                    controls.remove((Control) event.widget);
                }
            });
        }
    }
