As I found out the problem is actually different. The way I create
an image is the following

   add (new Image ("captcha", new CaptchaImageResource (100, 40, new
PropertyModel (this, "captchaValue"))));

   But it seems that an image does request an attached image resource
only first time it's created. I need it be rendered again and again
every time my page is rendered. How to achieve this goal?
