new bbcode - problem with switching in wysigw mode

[bartek24m]

I have problem with my new bbcode
I add up new bbcode [TESTT] with one conditions:

in includes/class_bbcode.php

before:

function handle_bbcode_img_match($link)

add:

PHP Code:

    function handle_bbcode_testt($code)
    {
        global $vbulletin, $vbphrase, $stylevar, $show;
if ($vbulletin->userinfo['userid'] == '0')
{
        return 'code 1';
}
else
{
        return 'code 2';
}

    } 


and before:

($hook = vBulletinHook::fetch_hook('bbcode_fetch_tags')) ? eval($hook) : false;

ADD

PHP Code:

    if ($vbulletin->options['allowedbbcodes'])
    {
        //[TESTT]
        $tag_list['no_option']['testt'] = array(
            'callback' => 'handle_bbcode_testt',
            'strip_empty' => true,
            'disable_smilies' => true,
            'disable_wordwrap' => true,
            'strip_space_after' => 2
        );
    } 


Problem is when my users write
[testt]something[/testt]
and after that they try to look up by switching in WYSIGW mode ()

the tagss disapper ! and they get just code 2 !
