URLLoader not working on Beta 2

Hi,
I took the code from http://blog.smartbear.com/post/10-10-01/extending-loadui---part-2/ and created the custom component URLLoader in loadUI 2.0 Beta 2. But looks like that component is not passing any URL from the text file that I have attached. I have changed the code as suggested from
message['URL'] = url
to
message['url'] = url
but I am not seeing any thing running in "web page runner" or the "table log"
I even populated "Web Page Address" in the "web page runner" but no use.

Can you please help?

Thanks
Akhilesh
