Epic #72584: sysext:impexp
Import: page imported but no content.
The import of the attached file (regardless of format) returns success but only imports the page but no content.
The content is a powermail form.
The import message tab lists errors of the form
0 => 'Possible error: tx_powermail_domain_model_field:1 had no new id assigned to it. This indicates that the record was not added to database during import. Please check changelog!' (175 chars)
(same as those at https://forge.typo3.org/issues/59055).
This error messages originate from sysext/impexp/Classes/Import.php:1018:
A trial to import the file with "Force ALL UIDs values" also created no entries but also did not create the message tab and messages.
So this makes exports/imports basically unusable.
