I'm also having the same issue and have tried a few ways to get around this. None of them have worked.
1st way: Tried to save label text to a local variable from Events menu. This does not week. (Bug?)
2nd way: I'm trying to use the localStorage.setItems function but I can't get the value from the list.
I've tried a lot of variations and none have worked:
1) alert(Appery("listUserId").text());
--- this gets only the first value in the list
2) alert( Appery('listUserId', this).text() );
---- this is null or undefined.
3) jQuery('[name="listUserId"]').text()
---- this returns the entire list of IDs
