Passing Variable Between Hooks in Same Class File

Question

I am trying to retrieve a value from one action hook to be displayed in admin page.

public function hookActionProductCancel($params)
{
    $this->response = "response";
}
public function hookDisplayAdminOrder($params) {
    $this->context->smarty->assign('response', $this->response);
    return $this->display(__FILE__, 'views/templates/admin/response.tpl');
}

I am not receiving the value "response" in response.tpl. Probably a small issue but I am not getting it right at the moment.

Any guidance is truly appreciated. Thank you.

You should just store the response to cookie and clear it before displaying it.

public function hookActionProductCancel($params)
{
    // code
    $this->context->cookie->mymodule_response = "response";
    $this->context->cookie->write();
}
public function hookDisplayAdminOrder($params) 
{
    // if no response stored in cookie do nothing
    if (!$this->context->cookie->mymodule_response) {
        return false;           
    }

    // assign response from cookie to smarty then clear response from cookie
    $this->context->smarty->assign('response', $this->context->cookie->mymodule_response);
    unset($this->context->cookie->mymodule_response);

    return $this->display(__FILE__, 'views/templates/admin/response.tpl');
}
