flashdata not working but userdata works

[eluser]DrWaky[/eluser]
I just do the same, the $this->session->flashdata('item') doesn't work with flasdata in CI 2.0.x I have no problem with $this->session->userdata('item') ... but I wanted a volatile data...

I think that it is a BUG, cause at user guide you can see:

To read a flashdata variable:

Code:

$this->session->flashdata('item');

but it doesn't work.
