Hi all,
i think i`ve the problem.
within the modMenu/ .... resolve.table.resolver file.
You have to change the very last line of case INSATLL
if ($object->xpdo) {
switch ($options[xPDOTransport::PACKAGE_ACTION]) {
case xPDOTransport::ACTION_INSTALL:
....
$manager->createObjectContainer('disUserNotification');
!!!!!! old wrong value > $manager->createObjectContainer('disParticipant');!!!!!
replacement -> $manager->createObjectContainer('disThreadParticipant');
break;
case xPDOTransport::ACTION_UPGRADE:
have fun
