Hi,
When you put the Jquery mask on an input field of a record with data type currency it does not take into account that the value in the field already has a decimal in it.
for instance:
In database: 1568756856.1234
When applying the following mask: "000,000,000,000,000.00"
it shows : 156,875,685,612.34
when you want to pass the record to be saved in the database the value is gone and the column in the record is 0.
In this case you would have to use a non predefined mask like this: "#,##0.0000".
Let me know if that helps.
