CakePHP and tinyint as boolean

Use TINYINT(2) instead. If the length is 1, Cake sees it as a boolean.

The proper way (CakePHP3), if anyone is still having this problem

Model\UsersTable.php

protected function _initializeSchema( Schema  $schema)
{
    //this is a bigInt(20) field (other same type known Cakephp problem)
    $schema->columnType('OtherField'  , 'string');

    //this is a tinyint field
    $schema->columnType('Type'        , 'integer');

    return $schema;
}
