TYPO3 Core

My patch add this functionality to page_overlay_record, but only when you copy direclty pages_language_overlay, not when you copy a page (it normal behaviour of typo3 when copied a record which has child records).

Patch set 2 for branch master of project Packages/TYPO3.CMS has been pushed to the review server.
It is available at https://review.typo3.org/48071

This would be a very useful feature for 7 LTS as well, if it worked... With the new RealURL, collisions unresolvable by editors are even more likely to occur by accident, so I tried to add that copy suffix using the following snippet in our ext_tables.php. While it works if I copy translated page properties in List mode, it does not apply when copying pages which renders it useless...

// use same copy title suffix for translated page properties as for original pages
// only applies if not defined by TYPO3 itself (or other extensions)
if (!isset($GLOBALS['TCA']['pages_language_overlay']['ctrl']['prependAtCopy']) && isset($GLOBALS['TCA']['pages']['ctrl']['prependAtCopy'])) {
    $GLOBALS['TCA']['pages_language_overlay']['ctrl']['prependAtCopy'] = $GLOBALS['TCA']['pages']['ctrl']['prependAtCopy'];
}

// hide translated page properties by default
$GLOBALS['TCA']['pages_language_overlay']['ctrl']['hideAtCopy'] = '1';

Not sure if it works this way in TYPO3 8 but if it only applies to explicitely copied page translations, not a translated page, this feature is pretty useless and the issue has not been resolved yet...

If TYPO3 8 got modified so it applies ctrl properties to pages_language_overlay if the page is being copied, it would be great if that patch could be backported to 7 as well.

Patch https://review.typo3.org/48071 works only if the copy is made directly copying a 'pages_language_overlay' record in the List module. Instead this bug report states that the problem is when a BE user copies a 'pages' record and this is the real useful case of adding a "(copy n)" to language overlays.
Sorry but this bug is not resolved.
