valueCouldNoBeSet is used in the validation. I mean in order to
validate a field that field needs to have first a value of that type.
Since we can not always convert from a String to a Number we have this
cases where we can not set the value. Validation will generate an
error messag rturned by Field.errorMessage (probably needs renaming).
I'm aware that you may already know that, just wanted to express this
again.
The bottom line, you are right :) ... I'll provide access to this.
