Page state is not persistent: it goes out of memory once the page is rendered.

You have to store the value elsewhere in order to reuse it. Where you save it depends on where you want to use it.

Some options:

  • Pass it through an URL. This might have security implications;
  • View state;
  • Session object storage;
  • Application object storage.
