TypeError: Cannot convert null to an object.

[Eliot Clingman]

HI,

I took the following example test:
   public void testWelcomePage() throws Exception {
       WebConversation     conversation = new WebConversation();
       WebRequest request = new GetMethodWebRequest( "http://www.meterware.com/servlet/TopSecret" );
      
       WebResponse response = conversation.getResponse( request );
       WebForm forms[] = response.getForms();
       assertEquals( 1, forms.length );
       assertEquals( 1, forms[0].getParameterNames().length );
       assertEquals( "name", forms[0].getParameterNames()[0] );
   }

..and changed it to point to my development site at http://localhost.  This caused the test to bomb.  This page has some javascript, which seams to be related to the exception.  I have httpunit 1.6 running in jre 1.4.1_02

  I got the following error I don't understand:

TypeError: Cannot convert null to an object. (httpunit; )
