TYPO3 - TCA in ext_tables.php check and TCA/Overrides for v8

Question

Updated ext_tables.php, TCA and TCA/Overrides for TYPO3 8LTS? I moved the TCA definitions from ext_tables.php to /TCA folder and the query in list view is working again:

Answer 1

It's not compatible.

You should do your TCA definition of tx_code_domain_model_code in: Configuration/TCA/tx_code_domain_model_code.php

The static template definition in: Configuration/TCA/Overrides/sys_template.php

And your plugin and flexform definition in: Configuration/TCA/Overrides/tt_content.php

Be aware that the $_EXTKEY variable is not defined in those files so you have to type the extension key yourself.
