TYPO3 Core

When a field value is changed by a wizard it is not evaluated to the configured 'eval' configuration.

Example:
Make `header_link` required

$GLOBALS['TCA']['tt_content']['header_link']['config']['eval'] = 'trim,required';

If you now create a new content element the header link field is marked as required. If you use the wizard to select a target page the field is not evaluated and still marked as "invalid".
If you edit the field and add a whitespace it gets evaluated correctly.
