Is there any field option, or way to detect when a field becomes full and stop accepting further input.
At the minute, when I get to the end of the field, the behaviour i'm seeing has the last character in the field overwritten by the new character when I call form_driver, I can't seem to find a setting to say ignore further characters it when full, or a reliable way of detecting when a field is already full to stop me calling form_driver.
Any help would be appreciated!
