[TYPO3] TS for users/user groups in ext_tables.php

[Tapio Markula]

Hi

I got an error message trying to use
in ext_tables.php TS for users/user groups.

In general detecting TS for users/user groups
works
$getTSConfigForAModuleName =
t3lib_BEfunc::getModTSconfig($this->pageinfo['uid'],'mod.ModuleName');

but that doesn't work inside ext_tables.php
and I don't figure how to get work.
If that would work I could add some user/user group level CSS-control 
for my skin.
