Ok... I see I think. Out of curiosity, why is this done this way out of the box? I understand it is meant to give you the ability to add multiple items to a given module instance, but does the Html control really even have that functionality? By definition, isn't the mapping 1:1 (Module:Item)? Just seems odd to me (Unless this is to give the "Click here to edit" functionality to the module?).

So because my module will never use this functionality, and the mapping will be 1:1, I can essentially remove the entire ItemId field and key on ModuleID, and remove all this non-sense, correct?

I can see where this would come in handy for another module Im writting though...
