Hi guys.
I've found a workaround. I can use scripting:
$.locale = "pl_PL" (or any other European)
with some logical restrictions naturally. I will have to check variable COUNTRY first.
Yet it's not a nice solution. I have to enter this script into each numeric field in the form, so if anyone knows the proper solution (SAPnote, ot print server settings), please share.
regards,
Michał
