Custom Form Element with custom ViewHelper

I would like to create a custom Form Element which is essentially a Textarea with some javascript to turn it into a WYSIWYG editor (using NicEditor). I thought the best way to do this would be would be something like this

PHP Code:


			
class Foo_View_Helper_FormNicEditor extends Zend_View_Helper_FormTextarea

{

    public function formNicEditor($name, $value, $value = null, $attribs = null)

    {

         $textarea = $this->formTextarea($name, $value, $attribs);

         return ..........

    } 

   

}

and then in my custom Form Element to set

PHP Code:


			
pubic $helper = 'formNicEditor'

...the problem of course being that it doesn't know where to find this ViewHelper.

What I settled on do was overwriting the render method as follows:

PHP Code:


			
public function render(Zend_View_Interface $view = null) 

{

         $view = $this->getView();

         $view->setHelperPath('Foo/View/Helper', 'Chintion_View_Helper');

         return parent::render($view);

}

This works, but it doesn't feel right to me...

you can set setHelperPath() whereever in the code. for example you can execute it in the action method where it will be used.

True, but I would prefer that the element live "self-sufficiently"...I want the element to be ready to be used anywhere in my application (and in any other application).

In my apps I set the view helper path in the bootstrap.

PHP Code:


			


$viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer');



$viewRenderer->initView();



//include our custom helpers

$viewRenderer->view->addHelperPath(APPLICATION_DIRECTORY . '/views/helpers', 'My_View_Helper');
