[Htmlunit-user] occaisional JS error

[Lodge, G. <Gar...@ac...>]

I get a periodic error that happens when I run a number of tests in
succession. If I run this test singley, it passes much more often.

Here's a guess at what might be caussing the problem (since the call is
getTopCallScope?). Included with the stack trace is a lot of javascript. At
the bottom of the javascript is this code:
     [echo] function onloadcalls(){
     [echo]     eval(onloadfunctions)
     [echo]     pageLoaded = true;
     [echo] }


this code executes after the page loads through this configuration

window.onload = function(){setTimeout("onloadcalls()",1)};


any ideas what might be causeing this error?
