I've allowed the addition of coments, so you can let me know what you think there.

I would also like to contribute this to somewhere where it can be worked on by more than just me and isn't so hidden away. Can anyone tell me where the best place to put this would be? Thanks, Craig -----Original Message----- From: Alejandro Scandroli [mailto:[EMAIL PROTECTED] Sent: Tuesday, 5 June 2007 5:59 PM To: Tapestry users Subject: Re: Cometd Implimentation Hi Craig Nice component!. I've tested it with 6.1.0 version of maven-jetty-plugin and It works fine! I'm testing it on linux and at first Tapestry complained about not been able to find a template for the Cometd component, it was because the html template name is lowercase. Once I changed that it worked. Is there a way to let you comments directly on the site? Saludos. Alejandro.
