[NTG-context] processallactionsinset and default

Hi! The "default" value works well for processaction but apparently does not for processallactionsinset. What am I missing? Example: \def\A{A} \def\XX{} \def\Un{Un} \processaction[\A][A=>Yeah!,default=>Def.,unknown=>Huh?]% \processaction[\XX][A=>Yeah!,default=>Def.,unknown=>Huh?]% \processaction[\Un][A=>Yeah!,default=>Def.,unknown=>Huh?] \processallactionsinset[\A,\XX,\Un][A=>Yeah!,default=>Def.,unknown=>Huh?] Output: Yeah!Def.Huh? Yeah!Huh?Huh? Thanks for any help, Christoph
