TYPO3 Core

I can reproduce this error. It seems that the initialization of $LANG is commented out.

from the index.php:

#unset($MCONF);
#require ('conf.php');
#require ($BACK_PATH.'init.php');
#require ($BACK_PATH.'template.php');
$LANG->includeLLFile('EXT:impexp/app/locallang.php');

Normally it would be initialized in template.php on these lines:

$LANG = t3lib_div::makeInstance('language');
$LANG->init($BE_USER->uc['lang']);

It seems that uncommenting these lines in /typo3/sysext/impexp/app/conf.php

define('TYPO3_MOD_PATH', 'sysext/impexp/app/');
$BACK_PATH='../../../';

and uncommenting these lines in /typo3/sysext/impexp/app/index.php

#unset($MCONF);
#require ('conf.php');
#require ($BACK_PATH.'init.php');
#require ($BACK_PATH.'template.php');

fixes the problem. I don't have a clue why these are commented but i guess the author had good reason for it..?

Found the changeset here:

http://svn.t3.digitaldistrict.de/cgi-bin/trac.cgi/changeset/5631#file29

The link to te module is wrong. From 4.1 in a module is expected to be called from typo3/mod.php.

eg http://typo3-dev.activesolution.at/sanochemia/typo3/mod.php?M=xMOD_tximpexp&tx_impexp[action]=export&tx_impexp[list][]=be_users

So the error is not in ImpExp, but in the list module.

Another error is in the drop down box from the clipboard (with the same reason).

Fixed in SVN.
