I am creating a Change Password form. I added a Dynamic Registration Module (V4.10.43) to a DNN (V5.6.3) page. I used the Setup Wizard to only add the Userid, Password and ConfirmPassword questions. I then added a fourth "Current Password" question and set the ShortName = ExistingPW. I made the Userid question read only. I also set the Module Configuration > Validation Configuration > Force
Existing Password for changing passwords = checked.
Using this form and filling in all three password fields with valid data, I always get the error
Error getting Password!... Object reference not set to an instance of an object.
If I remove the Force Existing Password requirement, it works, so it is something related to this option. What object needs to be set?
