ORM insert not working

[matesko]

mysql

take simple model (id is autoincrement field):

    $this->fields = array(
      'id'    => new DB_ORM_Field_Integer($this, array()),
      'tekst' => new DB_ORM_Field_String($this, array())
    );

this code does not insert:

    $model = DB_ORM::model('testt');
    $values = array(
      'tekst' => time());
    $model->load($values);
    $model->save();

if i set id nothing happens also.

if id value exists in database update is executed.

when following methods in Base_DB_ORM_Model are changed as such, it works.

but please do verify

// do not append $buffer if null value
// return null if buffer empty

    protected function hash_code() {
        $self = get_class($this);
        $primary_key = call_user_func(array($self, 'primary_key'));

            $buffer = '';
            foreach ($primary_key as $column) {
                if ( ! isset($this->fields[$column])) {
                    throw new Kohana_InvalidProperty_Exception('Message: Unable to generate hash code for model. Reason: Primary key contains a non-existent field name.', array(':primary_key' => $primary_key));
                }
                if ( ! is_null($this->fields[$column]->value)) {

                }

Yep, you are totally right. I really appreciate you taking the time to debug it and submit a fix.
