TYPO3 Core

Hello everybody,

I have just extended the pages table, like described here with tt_content: http://docs.typo3.org/typo3cms/TCAReference/ExtendingTca/Examples/Index.html
the TCA Overrides just appear in the TYPO3 Backend after I called them from ext_tables.php
with

include_once(TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extPath($_EXTKEY)."Configuration/TCA/Overrides/pages.php");

If it is ok to call the Configuration Overrides like this it would be nice to find it in the Documentation,
but if there is an if-clause needed (I just copied from the git-Version of direct_mail, there is an if-clause, depending on the tt_address version as it looks:

if (VersionNumberUtility::convertVersionNumberToInteger(TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getExtensionVersion('tt_address')) <= VersionNumberUtility::convertVersionNumberToInteger('2.3.5')) {

)

With the best regards,
Sabine
