title: Use activities for New Element Wizard
body: <p>I'm trying to use <code>org.eclipse.activities</code> in order to enable/disable a new element wizard(for example I want to hide the "new java Class wizard"). When I add the wizard ID to the activity, I can still select the the new element wizard from "Select a Wizard" and promts a dialog asking me if I want to enable this activity. How can I hide this wizard from the "Select a wizard" tree or disable the Confirm Enablement dialog?</p>
