What type of field do you have? Integer or number?
I tried to format both by setting the property like your example, but it also doesn’t work for me. Is it possible for you to take a text field and format the value by an onDataChange function?
my guess is that you need to use a mask so that ####,####,####,#### and so on the , is really not seen as a decimal or grouping symbol but more as a literal (which it kind of is)
should work fine (it is really not a number anyway…)
You can’t use that on real numbers at the moment, or you have to place a converter between it…
That converts from a number DB value to a String (and then use the above mask)
and converts from the String to the number db value again (but this is already pretty automatic)
