Unsupported or non-existing property name “…” used in relation matching

Changed Caching

Caching TCA information changed in TYPO3 v8.


From the core API docs:

The second way is to call \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::makeCategorizable(). This method adds a new entry into the registry managed by \TYPO3\CMS\Core\Category\CategoryRegistry. The registry will take care of adding the relevant $TCA definition to create a field for making relations to the system categories. The call to makeCategorizable() must be located in an extension’s Configuration/TCA/Overrides folder (or ext_tables.php file before TYPO3 CMS 6.2.1).

Wrong Relation

Use of 1:1 relation in domain model but querying it as a n:m relation.


The query must use equals() for 1:1 relation. If you use contains() extbase will expects a 1:n or n:m relation.
