TYPO3 Core

im writing a XCLASS-Extension and need some different description (locallang_csh.php). Therefore I use an other locallang_csh.php file and include it with:

t3lib_extMgm::addLLrefForTCAdescr('tx_aseventdb_events','EXT:ks_eventdb/locallang_csh.php');

But the help-window still displays the old Text...

investigating further I found that the TCA_DESCR-Array contains an Element

[refs] => Array
        (
            [0] => EXT:as_eventdb/locallang_csh.php
            [1] => EXT:ks_eventdb/locallang_csh.php
        )

but only the first file is loaded by lang.php when the method $LANG->loadSingleTableDescription($table); is called.

I fixed this issue by xclassing language::loadSingleTableDescription($table), where I replaced "$LOCAL_LANG = $this->includeLLFile($llfile,0,1);" with "$this->includeLLFile($llfile,1,1);" in line 352.
