Hi
When I Add a new Composite from: New->Other ->WindowsBuilder ->SWT Designer ->SWT ->Composite
it creates a new Coposite but when I go to the Design Tab I get this Error:

Exception during 'super' constructor evaluation

An exception happened during evaluation of constructor Composite(Composite,int) using arguments {<null>,0}.

java.lang.IllegalArgumentException: Argument cannot be null
	at org.eclipse.swt.SWT.error(Unknown Source)
	at org.eclipse.swt.SWT.error(Unknown Source)
	at org.eclipse.swt.SWT.error(Unknown Source)
	at org.eclipse.swt.widgets.Widget.error(Unknown Source)
	at org.eclipse.swt.widgets.Widget.checkParent(Unknown Source)
        ...

I check the code automatically generated:

	public AddBookComp(Composite parent, int style) {
		super(parent, style);

	}

I changed them over and over, for example I try this one:

 super(new shell(new Display(),SWT.NONE),SWT.NONE);

but the error still the same. how can I Use Design Tab to Design e Customized Composite?

in addition I use: Archlinux(x86_64), Kernel 3.0.3, KDE 4.7, Eclipse Indigo
