CFC’s are a wonderful thing in the world of Coldfusion Apps. They allow you append/display information without refreshing the page, deliver realtime queries of data, or display messages when users require guidance. They are wonderful until they break.
If you edit a query and get error messages, you either made a mistake and need to edit the CFC again, or are missing parameters.
If however your CFCs have been functioning fine for quite a while and you are suddenly getting errors on all your apps with CFC linked content, then you need to restart your CF services on your web server and reset the IIS connection too. If that does not clear the issue, make sure your database server is not the culprit. As a last resort check your browser. Did you upgrade or change it recently, which may have turned off Javascript functions.
