[BUG] Previewing in workspaces: Staged Versions is always empty

[nstungcom]

Hi 👋

I am currently testing container with workspaces and it seems like that previewing in the FE is not working as expected. The Staged Version is always empty when debugging renderedContent so nothing is showing in the FE.

This PR #88 removed these line in Classes/DataProcessing/ContainerProcessor.php and might be the cause of the bug:

if ($child['t3ver_oid'] > 0) {
    $conf['source'] = $child['t3ver_oid'];
} else {
    $conf['source'] = $child['uid'];
}

Manually re-adding these line back seems to work and previewing work as expected.

Specs:

• TYPO3 10 latest running in composer mode + PHP 7.4 using ddev
• container dev-master
