unwanted caching of custom component after j25 -> j33 - Joomla! Forum - community, help and support

i'm trying migrate selfbrewed component worked under j25 j33.
but having following problem:

calling output in old j25 installation delivers wanted (fresh) page:
http://j25.physiolution.at/index.php?co ... 2&tid=1730

while calling output in new j33 installation seems deliver somewhere cached output - cleaning browsers cache helps hitting reload while calling url not refresh called layout.
http://j33.physiolution.at/patienten?vi ... 2&tid=1730

i controlled adding

code: select all

echo date("d-m-y h:i:s");

to layout.

the component structured controller.php:

code: select all

<?php
defined('_jexec') or die();
jimport('joomla.application.component.controller');
class physiolutioncontroller extends jcontrollerlegacy{
  function display($cachable = false, $urlparams = false){
    parent::display($cachable);
  }
}

view.raw.php:

code: select all

<?php
defined('_jexec') or die('restricted access');
jimport('joomla.application.component.view');
class physiolutionviewpatienten extends jviewlegacy {
  function display($tpl = null){
   $this->id = $this->get('id');
   $this->pat_id = $this->get('pat_id');
        ...
   $this->filter = $this->get('filter');
    parent::display($tpl);
  }   
}

the view called in frontend registered user caching should prevented automatically joomla far read. caching turned off in backend.
can me?
