[Webtest] JavaScript exception using Prototype and Scriptaculous

[Matt Raible]

I'm using the prototype and scriptaculous JavaScript libraries in my 
application.  They seem to work great in a browser.  However, with 
WebTest build 544 (has HtmlUnit), I'm getting the following error.  It 
doesn't fail the test, so it seems harmless.  Is there anyway to 
surpress it, or is there something in prototype.js that I need to patch?
