zend framework 1 Form - Note element lost its value if there is validation error -

i have note element in zend framework 1 form used registration. defined in format:

$captcha_reload =   new zend_form_element_note('captcha_reload',                                   array('value'=>"<div id='captcha_reload_div'>                                                 <a href='javascript:return false;'                              id='change-image'>change text.</a></div>"));         $this->addelement($captcha_reload);                       

this element displays hyperlink , displays during registration page call.

the problem during form submission. note element doesn't displays (ie missing hyperlink) if there form validation error.

i have checked , tried code below:

$this->setdefaults(array('captcha_reload'=>"<div id='captcha_reload_div'>                                                 <a href='javascript:return false;'                              id='change-image'>change text.</a></div>"));  

but still there no value if there form validation error.

for note element, have included following in zend registration form page:

class zend_form_element_note extends zend_form_element_xhtml   {      public $helper = 'formnote';   } 

when form submitted over-riding value property of element. there nothing being submitted, when form echoed again show form errors, value of element nothing well.

perhaps adding isvalid function element?

// pseudo-code public function isvalid($value, $context = null) {   $this->_setvalue("<div id='captcha_reload_div'><a href='javascript:return false;' id='change-image'>change text.</a></div>");   return true; } 

this reset value custom text, , return true without doing checks (as know value want be). subsequently, when form echos again show value set in isvalid
