When a user clears the contents of a datWideMemo field that is exposed through data-aware controls it causes a Range Check Error. The user clears this field just by backspacing through the text until there’s none left, a moment later this error appears.
exception class : ERangeError
exception message : Range check error.

It only seems to affect one field in a particular table. Unfortunately that table is used in several parts of my application.
Any idea what might be the issue here ?
