You should add the code below before modifing a record

#Setup the language for GT::SQL.
local $GT::SQL::ERRORS->{ILLEGALVAL} = $self->_language('ADD_ILLEGALVAL');
local $GT::SQL::ERRORS->{UNIQUE} = $self->_language('ADD_UNIQUE');
local $GT::SQL::ERRORS->{NOTNULL} = $self->_language('ADD_NOTNULL');


Ensure that ADD_ILLEGALVAL, ADD_UNIQUE and ADD_NOTNULL are available in language.txt
