[TYPO3-dev] Adding BE columns from extension ?

[Steffen Kamper]

Hi list,

sry, i run in problems so often, so i have to post again.

When I add some BE-Columns, i can do this in localconf.php or in 
ext_tables.php.

But now i tried this in a BE-Modul in ext_tables.php and it seems to be to 
late - TCA Array is correct after it, but the BE Columns still the normal 
ones.
Here is the code:

$TCA['tt_content']['columns']['colPos']['config']['items']['4']['0'] = 
'SUB-LINKS';
$TCA['tt_content']['columns']['colPos']['config']['items']['4']['1'] = 4;
$TCA['tt_content']['columns']['colPos']['config']['items']['5']['0'] = 
'SUB-RECHTS';
$TCA['tt_content']['columns']['colPos']['config']['items']['5']['1'] = 5;

I tried to do with t3lib_extMgm::addTCAcolumns also, but same result.

Is there any way to add this columns "before" the columns are rendered or is 
there no way from extension ?
