Filter for a property inside a Composition inside an array is not executed

[wol-soft]

Describe the bug
Independent of a provided value or a default value the value for created is not transformed resulting in a fatal error when calling the generated getCreated:

Uncaught TypeError: ...::getCreated(): Return value must be of type ?DateTime, string returned

The issue also affects non-transforming filters like trim.

Expected behavior

The transformed filter should be executed and consequently a DateTime object should be returned.
