TYPO3 Core

Hello Mischa,
the thing you explained is not a Bug, flags are used as Sprites upon now.
Therefore only the ISO2 Code will be stored.
An UpdateWizard even modifies this for you if you are updating.

To exchange the flag-set you nowadays have to use the normal sprite Api to overwrite or exchange sprites (see Skinning manual).

So if flags are not shown in Backend, you either have a xclassed version of the form, which therefore is not capable of the new way or you are using iso-codes not within the sprite, for which you would have to register your icons anyways.

Could you please give us an insight?

Alternatively you can change line 137 to

$TCA['sys_language']['columns']['flag']['config']['items'][] = array($flagName, $flagName.'.gif', 'EXT:t3skin/images/flags/'. $flagName . '.png');

I recognized a problem with some ext, that use the filename in the table sys_language (e.g. templaVoila). While the file-ext is missing, the unknown.gif - Flag is shown.
That makes 4.5 a bit incopatible with older extentions.

But alternatively I can post a reference to this "bug" on the tv-Bugtracker.

I already moved your second report about the same problem, too the bugtracker.

This is indeed a breaking change to Extensions - there never has been a clean API to resolve flags.

So this one can be closed as for core, there is no bug.
