29 : @short declaration of special continuation for filter selection
30 : @descr Sometimes filter detection during loading document failed. Then we need a possibility
31 : to ask user for his decision. These continuation transport selected filter by user to
32 : code user of interaction.
33 :
34 : @attention This implementation could be used one times only. We don't support a resetable continuation yet!
35 : Why? Normally interaction should show a filter selection dialog and ask user for his decision.
36 : He can select any filter - then instances of these class will be called by handler ... or user
37 : close dialog without any selection. Then another continuation should be slected by handler to
38 : abort continuations ... Retrying isn't very useful here ... I think.
