Hi,
this looks like some js is executed in the context of an XmlPage rather
than an HtmlPage. If this is as expected, I would have awaited problems
earlier and if not then... Quite strange.
What is in the onready function? Where does the getElementById(..) occur?
<groovy>
com.gargoylesoftware.htmlunit.javascript.HtmlUnitContextFactory.debuggerEnabled
= true
</groovy>
should generate a lot of debug information (on function calls).
Otherwise, you have to set up your IDE to go with the debugger through
the execution.
Cheers,
Marc.

I've upgraded (again) to the latest snapshot of HtmlUnit, and the latest CR
of Rich Faces and still get the error below. Why would the root DOM object
be set to an XmlPage instance instead of an HtmlPage instance?
Any pointer on where to start debugging in HtmlUnit?

Using version R_1642 of webtest. I've tried with the libs released with
R_1642, and all combinations of the latest snapshot (12-10-2007) of
HtmlUnit and 1.6RC7 of rhino.
I'm trying to help test a Rich Faces application with some AJAX
components. I've turned up all WebTest logging and on the ajax form
submit I see the request go over the wire via XmlHttpRequest and then come
back with the expected XML response, with content-type of text/xml.
I see a log for "Calling onreadystatechange handler for state 4", and then
I get this error:

Relevant part of onreadystatechangehandler:
<pre>
if (_this._request.responseXML) {
_this._parsingStatus =
Sarissa.getParseErrorText(_this._request.responseXML);
if (_this._parsingStatus == Sarissa.PARSED_OK &&
Sarissa.setXpathNamespaces) {
Sarissa.setXpathNamespaces(_this._request.responseXML,
"xmlns='http://www.w3.org/1999/xhtml'");
}
}
if (_this.onready) {
_this.onready(_this);
}
</pre>
The framework is generating the response and all the javascript on the
frontend, so trying to break this down to a reproducable test case isn't
easy. I was hoping that some one on this list is using Rich Faces and
WebTest and may have a few tips.
I've seen previous bugs that have been fixed in HtmlUnit for
ClassCastException errors with XmlPage. Is this related?
