The key's set name argument is a string. You are passing Account.class.

Was the LDT map already created?
Was it created in the "userGroupMap" bin?

Good morning,

The LDT map is not created yet as the new account (e.g.: User A) is registered, and the map is scanned once the user login. However, this map store (system/other user request) for such user (User A) and it maybe clear if user read all of the msg (Stored in LDT map).

Now we have some workaround such as put a DUMMY record to the LDT Map/List bin, or get the record to check if the bin existed. However, all of the above solution have tradeoff on storage/performance. And some of the java developers used to check the map/set/list by compare to null value or get collection size. Thus i would like to know if there is any solution. Thanks

The LDT map will not be created unless items are added to it. Trying to obtain map configuration will not work for a non-existant map.

It's OK now, Thanks for your help. :)
