Flashdata boolean gets converted between requests

Hi all!

The topic pretty much says it all. I have this in a controller:

Code:

function delete($news_id)
{
    if ($this->News_Model->delete($news_id) === TRUE)
    {
        $this->session->set_flashdata('deleted', TRUE);
    }
    else
    {
        $this->session->set_flashdata('deleted', FALSE);
    }

    redirect(base_url().'admin/news/archive', 'location');
}

In the archive view I had this:

Code:

<?php if ($this->session->flashdata('deleted')): ?>

<?php if ($this->session->flashdata('deleted') === TRUE): ?>
<p class="success">News gelöscht!</p>
&lt;?php else: ?&gt;
<p class="error">News konnte nicht gelöscht werden!</p>
&lt;?php endif; ?&gt;

&lt;?php endif; ?&gt;

The inner if (the one that checks for TRUE) doesn't work. I examined the session and the flashdata item is actually '1', a string, not boolean TRUE.

Is this expected behaviour?
