> Problem:
> Changing the TCA (especially the columns-part of a table) via Tools-
> >Configuration breaks eg. the list module.
> Tools->Configuration writes strings like
> $GLOBALS['TCA']['tt_news']['columns']['image']['config']['allowed'] = 'jpg'; to
> typo3conf/extTables.php.
> 
> When this file gets included there may be the problem, that loadTCA has
> never been called, so the TCA array is incomplete.
> Furthermore if you set the columns part in extTables.php any proceeding call
> to loadTCA will not work, since 'columns' is already defined.
> 
> Solution:
> My patch adds a loadTCA call to extTables.php (if not already present) if a
> value for TCA is updated which does not go to ctrl part.
> 
> Kind regards
