So what doesn’t work is:
$sharedObj:=New Shared Collection
OB_CopyToSharedObject ($catalogObj;$sharedObj)
Use (Storage.MySharedCollection)
Storage.MySharedCollection.push($sharedObj)
End use
What does work is:
Storage.MySharedCollection.push(New shared object)
Use (Storage.MySharedCollection[Storage.MySharedCollection.length-1])
OB_CopyToSharedObject
($catalogObj;Storage.MySharedCollection[Storage.MySharedCollection.length-1])
End use
So it looks like you can’t .push() a shared object onto a shared collection.
