Object in session in MY_Controller clears the session completely.

[eluser]dakipro[/eluser]
Thanks, I checked the size and changed the database field for user_data to be longtext, still same issue. Session gets cleared the moment I add this object to the session, here is dump of the session

Code:

dump ($this->session) - File:  E:\www\application\controllers\admin\pages.php, line: 92;

                )

            [FlashNotice] => Array
                (
                    [info] => Array
                        (
                        )

                    [success] => Array
                        (
                        )

                    [warning] => Array
                        (
                        )

                    [error] => Array
                        (
                            [0] => validation_errors()
                            [1] => item_not_found_for_editing
                        )

                )

        )

    [CI] => stdClass Object
        (
            [__CLASS__] => Pages
            [mainObjName] => models\Page
        )

    [now] => 1305577038
)

After this is set in session, the moment redirection is done the entire part

Code:

[FlashNotice] => Array(
...

gets lost. This happens with flash_data as well, it gets lost if in MY_Controller __construct() I put this line

Code:

$laguagesData = array(
            'languages_default'=> $this->doctrine->em->getRepository('models\Language')->findBy(array('is_active'=>1))
        );
//this uses doctrine to get the object, its dump is visible in code I pasted above, it doesn't matter as it fails if I create plain object like
// 'languages_default'=> new models\Language();
$this->session->set_userdata('languagesActive',$laguagesData);

Again, if I remove this line from MY_Controller, or if I put this line

Code:

$laguagesData = array(
            'languages_default'=> 'Whatever string I want to put here'
        );

all works fine, session is preserved and this code exists on the next page

Code:

[FlashNotice] => Array
                (

After the old data is lost, I can confirm that session ID changes as well.

Here is the sample session cookie dump set in the browser

Code:

a:4:{s:10:"session_id";s:32:"c4297d0a493432155fb361828078c9a1";s:10:"ip_address";s:9:"127.0.0.1";s:10:"user_agent";s:50:"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0.1) Geck";s:13:"last_activity";i:1305577882;}fe3a99b94d7f4937d5edc6b335bfde18
//Note that this is not exact the same cookie from the dump above, but it is for the same code
