Incorrect error message during field value length validation

I'm getting "[b]Field value length is out of range, possible value length from to 255[/b]" error message, when value larger, then 255 symbols in length is entered as a field value.

It maybe be not obvious at first, but error message should end with "[b]from 0 to 255[/b]" instead of "[b]from to 255[/b]".

I'm proposing that we assume, that min/max field length is that error message is 0, when not set explicitly in field definition in unit config.
