No values received with map.add_entry_listener(include_value=False, ... #154
Description
Hi,
When subscribing for updates on a map, I'd like to not receive the old value to save the serialization overhead. As far as I can see from the docs, the include_value=False flag should allow me to do this [1], however when setting this to false I don't see the new value either.
def recv_event(event: EntryEvent):
print(type(event.value), type(event.old_value))
map.add_entry_listener(include_value=False, key=fid, added_func=recv_event, updated_func=recv_event)
# prints <class 'NoneType'> <class 'NoneType'>
map.add_entry_listener(include_value=True, key=fid, added_func=recv_event, updated_func=recv_event)
# prints <class 'dict'> <class 'dict'>

include_value – (bool), whether received events include an old value or not (optional).
