    Always One Selected Value when expression is used in a listbox

      Hi all!

       

      I have created a listbox where I use an expression for the field to be presented. It may be worth to note that the field has a prefix ('_') that is set to be hidden on the UI (SET hideprefix function). Altough this way my field is presented, I can not choose the option: Always One Selected Value (I select one value, so not selecting anything, where this function of course not works is not an issue). How can I achieve with this field that Always One Selected Value is an option? It's important that it remains hidden.

      Thanks for the help in advance!
