Extending Validation class to call a method that returns a modified value

[eluser]WanWizard[/eluser]
Odd.

Looking at the code in the _execute method, it does check for non-bool return values, on callbacks, internal PHP functions, and form_validation methods...

Code:

$this->_field_data[$row['field']]['postdata'] = (is_bool($result)) ? $postdata : $result;
