Bug #67875
Updated by Markus Sommer about 9 years ago
Currently the @tt_content@ table gets its @categories@ field by the install tool configuration value:
<pre>
$GLOBALS['TYPO3_CONF_VARS']['SYS']['defaultCategorizedTables']
</pre>
The problem here is that most of the content types are defined in @Configuration/TCA/Overrides@ since #65922.
Since the Overrides for the TCA are processed *after* the global categories are registered (in @ExtensionManagementUtility::buildBaseTcaFromSingleFiles()@), most of the content types are just left out when the @CategoryRegistry@ calls @ExtensionManagementUtility::addToAllTCAtypes()@.
