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

Use JSTL:

c: if test=${!empty wizard.progressBar}
logic iterate name=wizard property=pregressBar/logic:iterate
/c:test

Thanks Tim,

Hopefully the heads of state won't balk at the JSTL code. 

thanks again.
