Re: [Htmlunit-user] Urgent: JavaScript: getFrameset(""); returning null

[Marc G. <mgu...@ya...>]

Hi,

welcome to hmlunit.

The problem is that your js function getFrameset("bottom") returns null. I can't say more on it because you didn't 
provide its code.
The next issue that may appears, is that property cols of the frameset js object isn't implemented now in htmlunit. But 
this could possibly work because it will be set as a normal dynamic property on the object.

Please open a bug issue with this example and the code of your getFrameset function (reduced to the minimal is better).

Concerning the log messages, see:
http://htmlunit.sourceforge.net/faq.html#RedirectionDiagnosticMessages

The "Expected content type of text/javascript but got [text/html]" means that your webserver sends javascript files with 
an incorrect content type.

Marc.
