Insert a computed subform in a form, select its value type to Formula, in the programmer's pane type in a field name "a_id". The documents which will be presented by this form have a field "a_id". But the form doesn't have the hidden field named "a_id". If I use this kind of the form to display the document, will it work? I mean the form doesn't have the hidden field "a_id", but the document has. Will it work?
