Also, I am having troubles finding the correct “use” statements to have PHP recognize associateEntries()
$jgEntry->associateEntries()->setLabelHub($labelHub);
$jgEntry->associateEntries()->setLeaderOne($leaderOne);
Error: Call to undefined method Concrete\Core\Express\EntryBuilder::associateEntries()
This doesn’t make sense. associatedEntries() is in
/concrete/src/Entity/Express/Entry.php
and the entry stuff is in
/concrete/src/Express/EntryBuilder.php
