Anybody know this error...

I am getting this error and no further info. Also there is no error on the console nly on the browser - I have been trying to troubleshoot for a whole day with little success...

It happens when I click on a button to go to the next page. If anybody has even a clue of why this error occurs, please let me know..

Never mind - thanks..

I figured out that I had rendered=#{values} where values were returning Lists - I think they can only return boolean or Strings here..
