Hi Marc,

Looks like you were right (though it was a bit more subtle than that - hence no
errors or extra information on the console).

Looking at the JS code called by the link that was giving me trouble, I found:

if(typeof(eval("window.opener.portalHomeForm")) != 'undefined' ) { window.self.opener.viewStudio(); }

The conditional is supposed to evaluate to false in this case (and does in IE),
but in htmlunit and firefox it looks like it evaluates to true. As chance would
have it, this ends up calling viewStudio() for the wrong opener window - which
ended up firing an alert, which finally explains why the whole "Expected dialogs
but none found" thing kicked in.

I replaced it with

if(window.opener.document.getElementById("portalHomeForm"))

which seems to work. So I guess the problem wasn't with Webtest or even with
Htmlunit, but with our javascript code.

Thanks for the help,

Alex
