title: Eclipse Plugin: How to modify the extension "org.eclipse.ui.newWizards"?
body: <p>I have a wizard that should be launched in different ways: from the menu (<em>org.eclipse.ui.menus + org.eclipse.ui.actionSets</em>) and from the New context menu. For the later I used the extension <em>org.eclipse.ui.newWizards</em> to add the wizard into the context menu. So far, so good...</p>
  
  <p>For some reasons I had to subclass the wizard dialog (changed the finish button text in the dialog). If the wizard is launched from the menu, the action (defined in <em>org.eclipse.ui.actionSets</em>) creates and opens this special wizard dialog and everything is fine.</p>
  
  <p>If the wizard is launched from the context menu (<em>org.eclipse.ui.newWizards</em>), the internal class <em>NewWizardShortcutAction</em> is taken that creates the "normal" wizard dialog (and not my subclass) to open the wizard.  </p>
  
  <p>Is there any way to modify the implementation of the extension point that only my subclassed wizard dialog is used? </p>
