Not able to save records in registration form without the National ID

Hello All,

I am not able to save a record without entering a National Id for it during patient registration entry. I am getting a message “There was an unexpected issue on the server.Please try again”. I am able to save if the national id is entered. Would anybody suggest a workaround or the reason for the above issue? In fact , I have added two items as the options in National ID drop down.

Thanks.

Can you paste the full tomcat log at pastebin.com?
