i'm using http://docs.joomla.org/Developing_a_Model-View-Controller_(MVC)_Component_for_Joomla!1.6 to develop an extension, when i come to http://docs.joomla.org/Developing_a_Model-View-Controller_(MVC)_Component_for_Joomla!1.7_-_Part_06 part 6 i had a blanc page and the problem come from my site/models/library.php there is the code
Code:
<?php
   defined('_JEXEC') or die('Restricted access');
   jimport('joomla.application.component.modelitem');
   class LibraryModelLibrary extends JModelItem
   {
      protected $msg;
      public function getTable($type = 'Library', $prefix = 'LibraryTable', $config = array())
      {
         return JTable::getInstance($type, $prefix, $config);
      }
      public function getMsg()
      {
         if (!isset($this->msg))
         {
            $id = JRequest::getInt('id', 1);
            $table = $this->getTable();
            $table->load($id);
            $this->msg = $table->title;
         }
         return $this->msg;
      }
   }


i think problem come from $type = 'Library', $prefix = 'LibraryTable', my table name is ebook_livre, what should i mention us $type and $prefix ? or is there any other reasons ?

If you are developing in Joomla 1.6/1.7, the constructor of the class JTable in libraries/joomla/database/table.php accepts the following parameters:
Code:
    * @param   string Name of the table to model.
    * @param   string Name of the primary key field in the table.
    * @param   object JDatabase connector object.
These parameters are different from the 1.5 version of the JTable constructor, which for some reason is in the 1.7 example. This difference can cause the problem. You will most likely find some error codes in the PHP error log, if you have configured the errors to be logged.
