What steps will reproduce the problem?
1. Logon.
2. Select "Setup Password Responses"
3. Fill the password responses
4. Click in "Save Responses"
5. CLick in "Go Back" to change responses again.

What is the expected output? What do you see instead?
I expected the page with field to change my responses, but I received a error: 
"PWM 5015 - Unexpected error. If this error occurs repeatedly please contact 
your helpdesk. { 5015 ERROR_UNKNOWN (java.lang.NullPointerException) }"

What version of PWM are you using?
I download the trunk version (last).
