Does the validation by calculation takes place only when commiting a record
and not when changing the contents of field?

Validation takes place when you try to exit the field ... as long as
you turn on the option to check whenever the field is changed.

If you leave that option turned off, then FileMaker will only check the
initial data, not future changes to it.
