How can I get a Shell from inside a handler [message #906537]

I want to open a WizardDialog from a Handler.
So I am doing this and it works:

@Execute   
public void execute(){  
	System.out.println("Called");  
	WizardDialog dlg = new WizardDialog(new Shell() , new MyWizard());  
	if(dlg.open() == Window.OK){			  
        }		  
}

But should I be doing new Shell()? I don't know since I am newbie in RCP/SWT.
I thought to use the current Shell so I did:

WizardDialog dlg = new WizardDialog(PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell(), new MyWizard());

But I got exception:
Quote:

org.eclipse.e4.core.di.InjectionException: java.lang.IllegalStateException: Workbench has not been created yet.

Note that my main window is open and I press the menuitem button and from its handler I try to open the WizardDialog. How is it possible that the Workbench is not initialized at this point? I see the window!
Could you please help me out?

@Execute
public void execute(Shell shell){
System.out.println("Called");
WizardDialog dlg = new WizardDialog(shell , new MyWizard());
if(dlg.open() == Window.OK){
}
}
