TYPO3 Core

The update wizard currently stops, when the result (amount of rows updated) is zero. This scenario can happen, when the current FlexForm field actually does not contain the expected structure (e.g. really old content elements, that have never been saved with FlexForm values) and the update query actually will write the same content to the field, that is actually present in the database row.

The updater should just silently ignore, that no row has been updated, so following plugins can be migrated successfully.
