I think I discovered a bug in the SES.cfc interceptor. I have a handler called blog.cfc with an action called ‘rss’ the path looks like http://mydomainname.tld/blog/rss/
and the SES.cfc on line 459 throws the following error:
Error Type: Expression : [N/A] Error Messages: The 2 parameter of the Left function, which is now -1, must be a positive integer
I dumped the variables in the function detectExtension and saw that getValidExtensions() has rss listed as a valid extension which matches my action. I believe that is the problem.
