Iterate of List - need to test if list is null

[sean jones]

I have an object named "Wizard" in the request. 

Wizard has a property defined as

pubic Class Wizard {
      private List progressBar = null;
      public Wizard() {}
      public List getProgressBar() { return progressBar; }
}

in JSP i do this

<logic:iterate name="wizard" property="progressBar">
</logic:iterate>

how can i test if the progressBar is null before i start the iterate.

right now i get an error, cant find collection.  

i tried to used <logic:notEmpty> but i am not using struts 1.1
