i want initialize class error 324 (net::err_empty_response)

this class want initialize:

<?php class cms_content_item_page extends cms_content_item_abstract { public $id; public $name; public $headline; public $image; public $description; public $content; }

and class extends from:

<?php abstract class cms_content_item_abstract { const no_setter = 'setter methode bestaat niet'; public $id; public $name; public $parent_id = 0; protected $_namespace = 'page'; protected $_pagemodel;  public function __construct($pageid = null) {     $this->_pagemodel = new cms_content_item_page();     if(null != $pageid)     {         $this->loadpageobject(intval($pageid));     } }  protected function _getinnerrow($id = null) {     if($id == null)     {         $id = $this->id;     }     return $this->_pagemodel->find($id)->current(); }  protected function _getproperties() {     $propertyarray = array();     $class = new zend_reflection_class($this);     $properties = $class->getproperties();     foreach($properties $property)     {         if($property->ispublic())         {             $propertyarray[] = $property->getname();         }     }     return $propertyarray; }  protected function _callsettermethod($property,$data) {     $method = zend_filter::filterstatic($property, 'word_underscoretocamelcase');     $methodname = '_set' . $method;     if(method_exists($this,$methodname))     {         return $this->$methodname($data);                }        else     {         return self::no_setter;      } }  public function loadpageobject($id) {     $this->id = $id;     $row = $this->getinnerrow();     if($row)     {         if($row->namespace != $this->_namespace)         {             throw new zend_exception('niet in staat om pagina type te weergeven:'              . $row->namespace . ' naar type:' . $this->_namespace);         }         $this->name = $row->name;         $this->parent_id = $row->parent_id;         $contentnode = new model_contentnode();         $nodes = $row->finddependentrowset($contentnode);         if($nodes)         {             $properties = $this->_getproperties();             foreach($nodes $node)             {                 $key = $node['node'];                 if(in_array($key,$properties))                 {                     $value = $this->_callsettermethod($key,$nodes);                     if($value === self::no_setter)                     {                         $value = $node['content'];                     }                     $this->$key = $value;                 }             }         }     }     else     {         throw new zend_exception("niet in staat om content item te laden");     } }  public function toarray() {     $properties = $this->_getproperties();     foreach($properties $property)     {         $array[$property] = $this->$property;     }     return $array; }  public function save() {     if(isset($this->id))     {         $this->_update();     }     else     {         $this->_insert();     } }  protected function _insert() {     $pageid = $this->_pagemodel->createpage(         $this->name,$this->_namespace,$this->parent_id);     $this->id = $pageid;     $this->_update(); }  protected function _update() {     $data = $this->toarray();     $this->_pagemodel->updatepage($this->id,$data); }  public function delete() {     if(isset($this->id))     {         $this->_pagemodel->deletepage($this->id);     }     else     {         throw new zend_exception('niet in staat om item te verwijderen; het item leeg!');     } } }

and in script i'm trying initialize class:

    public function createaction() {     $pageform = new form_pageform();     $pageform->setaction('/page/create')              ->setmethod('post');     if($this->getrequest()->ispost())     {         if($pageform->isvalid($_post))         {             $itempage = new cms_content_item_page();             $itempage->name = $pageform->getvalue('name');             $itempage->headline = $pageform->getvalue('headline');             $itempage->description = $pageform->getvalue('description');             $itempage->content = $pageform->getvalue('content');             if($pageform->image->isuploaded())             {                 $pageform->image->receive();                 $itempage->image = '/images/upload' . basename($pageform->image->getfilename());             }             $itempage->save();             return $this->_forward('list');                  }     }     $this->view->form = $pageform; }

in abstract class cms_content_item_abstract::__construct()

change  $this->_pagemodel = new cms_content_item_page();      $this->_pagemodel = new model_page();

i encountered problem in book "zend cms project", bet caused author's mistyping.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
