Important: The select item helper passes the field TSconfig 

Description 

GetSelectItemsForTcaManagedTableFieldMethodTrait::getSelectItemsForTcaManagedTableField() resolves the items of a TCA select outside FormEngine, by calling the field's itemsProcFunc handler with a parameter array it assembles itself. That array is meant to look like the one FormEngine passes, and in one entry it did not: $parameters['TSconfig'] held the complete page TSconfig tree of the current page.

FormEngine passes something narrower there: the content of the field's itemsProcFunc. page TSconfig, with that key already stripped, and null when the field has none. The helper now passes the same.

# The part a handler receives in $parameters['TSconfig']
TCEFORM.tx_academicjobs_domain_model_job.type.itemsProcFunc {
    mySetting = 1
}

Impact 

A handler that reads a setting of its own from $parameters['TSconfig'] found nothing when it was called through this helper, and works now. No handler of these extensions read that entry before, so nothing this package ships changes behaviour.

A project handler that compensated for the old shape, by descending through $parameters['TSconfig']['TCEFORM.'] itself, has to be adjusted: it now receives the subtree directly, or null . A handler that also serves the backend form already expects that shape, because FormEngine always passed it.

// Before, only through this helper
$mySetting = $parameters['TSconfig']['TCEFORM.'][$table . '.'][$field . '.']['itemsProcFunc.']['mySetting'] ?? null;

// After, the same as in FormEngine
$mySetting = $parameters['TSconfig']['mySetting'] ?? null;

Affected Installations 

Installations with an own itemsProcFunc handler that is reached through this helper and reads page TSconfig. The helper is used by fgtclb/academic-jobs for the job form of its frontend plugin.
