Hi,
I have a SharePoint list form using Nintex form. What I am trying to achieve is that the form has a participant field and it should default to current logged in user and should be not editable by user. The form displays the default value of the current logged in user when I set the default value to the current user from the common properties. However, when I save the form, the default value doesn't save. Is this a known bug? Also, how can I invalidate the form if same user is creating another form? I want to restrict one entry per user. Is there a way to validate this on the form?
