Form validation's set_value stopped repopulating

[eluser]Jason Tan Boon Teck[/eluser]
I found that somehow, set_value() hangs onto the values retrieved from POST, ignoring any reassignments in the controller. So I got it to work by subsequently pushing the new values back to the POST array and pulling back the values from this updated array.

Is this a bug?

Controller ehr_individual.php snippets:

Code:

$data['init_birth_date']        =   $this->input->post('birth_date');
$data['init_birth_date_estimate'] =   $this->input->post('birth_date_estimate');
$data['init_age']              =   $this->input->post('age');
...
// echoing from controller just for debugging purposes
if(($data['init_birth_date_estimate'] == "TRUE") && ($data['init_age'] > 0)){
    echo "Compute birth date based on age";
    $age                        =   "-".floor($data['init_age']*365.2425)." days";
    $data['init_birth_date']    =   date("Y-m-d", strtotime($age));
    echo "<br />data['init_age']=".$data['init_age']." <br />data[init_birth_date]=".$data['init_birth_date']." <br />age=".$age;
} elseif(($data['init_birth_date_estimate'] == "FALSE") && (!empty($data['init_birth_date']))) {
    echo "Compute age based on birth date";
    $data['init_age']  = round((time()-strtotime($data['init_birth_date']))/(60*60*24*365.2425),1);
    echo "<br />data['init_age']=".$data['init_age']." <br />data[init_birth_date]=".$data['init_birth_date'];
} else {
    echo "E R R O R";
