[TYPO3-dev] sys_categories: API conflicts with core

For a custom table of your own, you should not need an override file. 
You can put everything in /Configuration/TCA/table_name.php. The latter 
is expected to return an array, but you can execute other PHP code 
before returning, for example calling 
ExtensionManagementUtility::makeCategorizable(). However I haven't 
tested this scenario, so I'm not sure if it works fine.

Recently I stumbled on an issue when calling 
ExtensionManagementUtility::makeCategorizable() from a 
/Configuration/TCA/Overrides file, in that the categories field is 
there, but the Category Registry is not filled properly (it is probably 
not initialized properly when the TCA is loaded from cache). As I'm not 
exactly sure how this all works, I haven't dug into that yet. As a work 
around I placed my call ExtensionManagementUtility::makeCategorizable() 
in the extension's ext_tables.php file, which I recommend for now.

Cheers
