Ich hab das Script mal überprüft, das Designer einfügt, um Pflichtfelder zu validieren.

Was auffällt ist, dass in Zeile 46 die Variable sSOM von xfa.[0].form[0] auf xfa[0].template[0] geändert wird.
Da das Template ja statisch ist, und sich zur Laufzeit gar nicht verändern kann, hat man natürlich das Problem, dass bei sich wiederholenden Objekten im Template gar keine passende Instanz existiert.
Dadurch ist sSOM null. Da sSOM gleich dannach für die Variable oOriginalNode benutzt wird, die dann per resolveNode aufgelöst wird, scheitert das Ganze dann.
Wenn man diese Zeile auskommentiert oder löscht, funktioniert das Script auch mit sich wiederholenden Objekten.
Code: Alles auswählen
sSOM = sSOM.replace("xfa[0].form[0]", "xfa[0].template[0]");
