ya, there is a lot of debate about the value in put null entries in lists and dictionaries but they have that requirement but for whatever reason they want that so Im just seeing whats possible. In the relational world it doesnt make much sense but they are just thinking more of the state of an object, ie, they save it with 5 entries and they get that exactly back when its reloaded regardless if some of the entries are null.
