--
-- Table structure for table `pages`
--

CREATE TABLE IF NOT EXISTS `pages` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(200) NOT NULL,
  `title` varchar(200) NOT NULL DEFAULT '',
  `text` longtext,
  `enabled` smallint(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 ;

form

class Admin_Form_Page extends Zend_Form
{
    public function __construct($options = null)
    {
        parent::__construct($options);
        $this->setDisableLoadDefaultDecorators(true)
            ->setElementDecorators(array(
                'ViewHelper',
                'Label',
                'Errors',
                array('HtmlTag', array('tag' => 'p'))
            ));

        $this->setDecorators(array(
            'FormElements',
            'Form'
        ));

        // Add Elements

        $this->addElement('hidden', 'id', array('decorators' => array('ViewHelper')));

        $this->addElement('text', 'name', array(
            'label' => 'Название страницы',
            'required' => true
        ));

        $this->addElement('text', 'title', array(
            'label' => 'Заголовок страницы',
        ));

        $this->addElement('textarea', 'text', array(
            'label' => 'Текст страницы'
        ));

        $this->addElement('checkbox', 'enabled', array(
            'label' => 'Страницы включена'
        ));

        $this->addElement('submit', 'save', array(
            'label' => 'Сохранить',
            'decorators' => array(
                'ViewHelper',
                array('HtmlTag', array('tag' => 'p'))
            )
        ));
    }
}

and model

class Default_Model_Pages extends Zend_Db_Table
{
    protected $_name = 'pages';

    protected $_cols = array('id', 'name', 'title', 'text', 'enabled');

    protected $_primary = 'id';

    public function getPagesList($enabled = true)
    {
        $sql = $this->select();
        if (true === $enabled) $sql->where('enabled = 1');
        return $this->fetchAll($sql)->toArray();
    }
}

then i wont create new page with Zend_Db_Table_Row

...
$pageData = $pageForm->getValues();
$id = (!empty($pageData['id'])) ? (int) $pageData['id'] : null;

$pageRow = (null === $id)
    ? $pageTable->createRow($pageData)
    : $pageTable->fetchRow($pageTable->select()->where('id = ?', $id))->setFromArray($pageData);

if ($pageRow->save()) {
    $this->view->content = '<p class="info">Save Ok</p>';
} else {
    $this->view->content = '<p class="error">Save error</p>';
}

i have error

I think that the problem is due to the fact that you assign $_cols variable yourself. When you do this, the Zend_Db_Table is not properly initialized. According to the Zend Framework reference to specify columns you should overwrite describeTable() method:

_setupMetadata() sets the schema if the table name contains the pattern "schema.table"; calls describeTable() to get metadata information; defaults the $_cols array to the columns reported by describeTable(). By overriding this method, you can specify the columns.

EDIT: Some more insight.

Specifically your Default_Model_Pages is not properly initialized, because the _setupMetadata() of Zend_Db_Table_Abstract is not executed. Normally it is executed when _primary or _cols variables are not set. Because, in your Default_Model_Pages you manually set these two variables, the _setupMetadata is not run. This is also the reason why everything worked when you removed protected $_primary = 'id'; from your class. In that case $_primary was not set, and subsequently, _setupMetadata() was called within _setupPrimaryKey() method.

you can get the cols via:

$table = new YourTable();
$cols = $table->info(Zend_Db_Table_Abstract::COLS);

or just use below in your model file:

$this->info(Zend_Db_Table_Abstract::COLS)
