[Webtest] Re: AJAX (DWR) webtest Compatability

[Marc Guillemot]

Hi Richard,

this comes from a currently incomplete implementation of XMLHttpRequest 
in htmlunit. To be more precise the responseXML is not totally mapped to 
be accessed using the normal JS syntax. In your case it is probably the 
nodes that can't be accessed with syntax "nodes[0]".

Marc.
