I have the same problem.
In Italy the comma is used ad decimal separator, but on the keypad
is present a dot. All major softwares transform this dot in a comma during input so the user can use only the keypad.
In Servoy this seems not possible.
It could be possible if every field have a KeyPress event where we can intercerpt and modify the key (as I asked in another post).
Yes, this is indeed a problem for our customers. It is not a problem of Servoy, but a problem using locale: NL or Italy or whatever with US keyboards. Filemaker etc.. has this same issue.
