I understand what you mean Adrian, and if I just had values already in hand to populate the MetaValue objects I would be golden. :) The problem really occurs because of our code needs to adapt between complex MetaValue/MetaType objects and our ProperyMaps and PropertyLists objects. I need to recurse level by level without knowing any specifics or having the entire structure of values in hand. I need to have the MetaValue object with the structure there so I can generally recurse through the complex object and create correct types within the structure. Then set values. I have a long workaround that is currently working. However, having the ability to create an empty complex MetaValue object would save a lot of extra work. Now, I think we can wait though on this and see how things work out, to see if the current code I have causes any issues.
