@ymichalak yes it is possible to set the presentation in vRA after the fact. OGNL is a way of calling action and hiding fields based on conditions etc. but its far more efficient than setting all of it in XaaS form editor. A big bonus is if you refresh the form you dont have to go back through and set all the values again, The starting framework is pulled in from vRO you can then modify this if you wish. see vRealize Automation - XaaS Forms - YouTube  all the forms are pure vRO presentation and OGNL, looks just as good as any XaaS form.
