[HtmlUnit] [htmlunit:bugs] Re: #1996 com.gargoylesoftware.htmlunit.ScriptException: Exception invoking send

Maybe yes;

I need the real cause of the problem. Can you please set a JavaScriptErrorListener for your client and implement the method scriptException() in your error listener. Then debug or make sure to dump the whole throwable parameter including all cases.

Background: In Rhino all the js support is implemented in Java methods, and these methods are called via reflection. In your case one of the java methods throws an error (e.g NPE) but this error is wrapped as cause along the way up to rhino. I need this cause to figure out what is going on.
