Hi Yvan,

You should try the /new refinement :


view layout[
  text "Titel" FTitel: field
  button "OK" [either empty? FTitel/text
              [
                view/new newlay: layout
               [
                text "Enter Title"
                button "OK" [unview newlay focus Ftitel]
               ]
              ]
              [unview/all]
 ]]

But you can also use 'flash like this :

view firstlay: layout[
  text "Titel" FTitel: field
  button #"^M""OK" [either empty? FTitel/text
              [
                fl: flash "Enter Title"
                wait 0.5 unview/only fl
                focus FTitel
              ]
              [unview firstlay]
 ]]

Notice the #"^M" that lets you action the button by pressing "Enter" 

Hope this will help you.

Best regards

Ronald
