Magento 1.9 Aamin Form

I’m tryng to add an admin form with no success. To do this i use a controller. If I add this code to the controler:

public function indexAction() {      $  this->loadLayout();     $  this->_setActiveMenu('ebay_menu');     $  block = $  this->getLayout()     ->createBlock('core/text', 'example-block')     ->setText('<h1>This is a text block</h1>');     $  this->_addContent($  block);     $  this->renderLayout(); }  

it works.

But if i try to show a form doesn’t:

public function indexAction() {      $  this->loadLayout();     $  this->_setActiveMenu('ebay_menu');     $  this->_addContent($  this->getLayout()->createBlock('ebaysync/adminhtml_form_edit'));     $  this->renderLayout(); } 

The form’s blocks are:

/app/code/local/Bileamara/EbaySync/Bloacks/Adminhtml/Form/Edit.php

class Bileamara_EbaySync_Block_Adminhtml_Form_Edit extends Mage_Adminhtml_Block_Widget_Form_Container {      /**      * Constructor      */     public function __construct()     {         parent::__construct();         $  this->_blockGroup = 'ebaysync';         $  this->_controller = 'ebaysync_orders';         $  this->_headerText = Mage::helper('ebaysync')->__('Ebay Orders Paid Not Shipped');         $  this->_removeButton('back');         $  this->_removeButton('reset');         $  this->_removeButton('save');     }  } 

/app/code/local/Bileamara/EbaySync/Bloacks/Adminhtml/Form/Edit/Form.php

class Bileamara_EbaySync_Block_Adminhtml_Form_Edit_Form extends Mage_Adminhtml_Block_Widget_Form {     /**      * Preparing form      *      * @return Mage_Adminhtml_Block_Widget_Form      */     protected function _prepareLayout()     {         parent::_prepareLayout();     }      protected function _prepareForm()     {         $  ebaystores = array('x','y');         foreach ($  ebaystores as $  ebaystore){             $  userToken = Mage::helper('ebaysync')->getToken($  ebaystore);             $  orders[$  ebaystore] = Mage::getModel('ebaysync/api')->getSellingManagerSoldListings($  userToken);         }          $  form = new Varien_Data_Form(             array(                 'id'     => 'edit_form',                 'action' => $  this->getUrl('*/*/post'),                 'method' => 'post',             )         );          $  form->setUseContainer(true);         $  this->setForm($  form);          $  helper = Mage::helper('ebaysync');          //configurazione         foreach($  ebaystores as $  ebaystore){              $  fieldset = $  form->addFieldset('config', array(             'legend' => $  helper->__('Ebay Store: ').$  ebaystore,             'class' => 'fieldset'             ));             foreach ($  orders[$  ebaystore]->SaleRecord as $  order){                 $  fieldset->addField('order_ids', 'checkbox', array(                 'label' => $  order->SaleRecordID,                 'name' => 'order_ids',                 'value' => $  order->SaleRecordID.'*'.$  order->SellingManagerSoldTransaction->OrderLineItemID                 ));             }         }          return parent::_prepareForm();     } } 

Can anybody tell me what is wrong?
