I recently updated our site from Sitecore 6.3.1 to the latest 6.6 release. Now my custom dialog app is giving me a "Page Not Found" error.
It lives in sitecore/shell/Applications/Dialogs along with all of the built-in Sitecore tools accessible in Content Editor: Publishing, CopyTo, Clone, etc. These are working fine.
Did 6.6 change the way these paths are resolved? Do I need to add my custom application name to a config somewhere? All files are in place... and the code is definitely up to date. The class declaration is public class LanguagePopUpForm : DialogForm
. Is DialogForm still valid here?
