Re: [Htmlunit-user] com.gargoylesoftware.htmlunit.ScriptException: Exception invoking Node.addEventListener() with arguments [String, NativeObject, Boolean]

[Ahmed A. <asa...@ya...>]

Hi Sridhar,

The exception has all the details, Node.addEventListener() is being called with (String, NativeObject, Boolean), however, HtmlUnit expects (String, Function, Boolean).

MDN hints that listener "must be an object implementing the EventListener interface, or simply a JavaScript function." [1].

With a quick search, I couldn't find an example of 'Object implementing EventListener", as all examples are Functions.

You should be able to quickly search your JS for "addEventListener", and get a small test case which works in real browsers with a listener not of a Function type.

Hope that helps,

Ahmed

Hi Team,

I'm using latest HTMLUnit_2.14 jars, but  I'm getting following expcetion.For more details about the exception please refer the attached doc.
Can you guys help me what is the root 
cause of this exception and how to fix it?  Also can you add the element
 details to the exception stack trace, which is causing the issue so that it would be
 easy to debug.
