Some people have reported not being able to log in to the ColdBox Dashboard. I have reproduced the error and it seems releated with the ses support that is NOT used in the app. So I have registered it as a bug for a patch release on 2.2.3. However, if you would like to make it work, you can do the following:

1. Open the {App}/config/routes.cfm

2. Change the following:

Change it to FALSE

That way the ses interceptor will not be intercepting calls. This is also a good point to mention that if you use the SES interceptor, then you need to code your apps for SES!. You can't have half ses and half not ses. You need to apply the ses best pracitces, especially on form submits.
