TYPO3 Core

I finally found the cause to this issue:

I am using typoscript to extract page information for Facebook OpenGraph (http://blog.typodrive.com/2014/07/22/opengraph-tags-in-typo3/) like this:


page.2 = LOAD_REGISTER
page.2.pageMedia.cObject = IMG_RESOURCE
page.2.pageMedia.cObject {
file {
import = uploads/media/
import.data = levelmedia:-1, slide
treatIdAsReference = 1
import.listNum = 0
import.override.field = media
}
}


Since FAL import.override.field does not work anymore and leads to the error in question. As described here (http://jweiland.net/typo3/typoscript/bild-aus-den-seiteneigenschaften-auslesen-ab-typo3-60.html) the right way to do is this:


page.2 = LOAD_REGISTER
page.2.pageMedia.cObject = IMG_RESOURCE
page.2.pageMedia.cObject {
file {
import.data = levelmedia:-1, slide
treatIdAsReference = 1
}
}


I think this is an Error in the FAL Extension.
Sometimes is the media Field in $GLOBALS['TSFE']->tmpl->rootLine only 1. And sometimes there is the right value like 1432.

    [1] => Array
        (
            [pid] => 1
            [uid] => 2
            [t3ver_oid] => 0
            [t3ver_wsid] => 0
            [t3ver_state] => 0
            [title] => Home
            [alias] => 
            [nav_title] => 
            [media] => 1
            [layout] => 0
            [hidden] => 0
            [starttime] => 0
            [endtime] => 0
            [fe_group] => 
            [extendToSubpages] => 0
            [doktype] => 1
            [TSconfig] => 
            [storage_pid] => 583
            [is_siteroot] => 0
            [mount_pid] => 0
            [mount_pid_ol] => 0
            [fe_login_mode] => 0
            [backend_layout_next_level] => 
            [tx_realurl_pathsegment] => 
            [tx_realurl_exclude] => 1
            [tx_realurl_pathoverride] => 0
            [tx_typo3blog_blogrolls] => 
        )

I don't know where the value be set.

The Problem is the FE Cache. The field media in Pages often not resolved with sys_file_reference and returns a 1.
My Patch check if the field media is a 1 and get the right value from the table sys_file_reference.

Thanks for your patch. The intention is correct however unfortunately not the patch. The "1" in this regard is the reference count, telling that one image is being used in a particular field.
The proper place for resolving these rootline values can be cound in the class RootlineUtility.
