Bug #85531
Updated by Mathias Brodala over 6 years ago
When editing a translated record which contains a @db@ field whose @l10n_display@ is configured as @defaultAsReadonly@ an exception occurs:
<pre>
#1476107295: PHP Warning: Invalid argument supplied for foreach() in /.../typo3/sysext/backend/Classes/Form/Element/GroupElement.php line 158 (More information)
TYPO3\CMS\Core\Error\Exception thrown in file
/.../typo3/sysext/core/Classes/Error/ErrorHandler.php in line 107.
17 TYPO3\CMS\Core\Error\ErrorHandler::handleError(2, "Invalid argument supplied for foreach()", "/.../typo3/sysext/backend/Classes/Form/Element/GroupElement.php", 158, array)
/.../typo3/sysext/backend/Classes/Form/Element/GroupElement.php:
00156: }
00157: } elseif ($internalType === 'db') {
00158: foreach ($selectedItems as $selectedItem) {
00159: $tableWithUid = $selectedItem['table'] . '_' . $selectedItem['uid'];
00160: $listOfSelectedValues[] = $tableWithUid;
</pre>
The code here expects an array but gets an integer (number of related records) instead.
This is triggered by the @SingleFieldContainer@ which replaces the @databaseRow@ @row@ value prepared by @TcaGroup@ with the raw value from @defaultLanguageRow@ in case @l10n_display@ is set to @defaultAsReadonly@.
