[Dojo-interest] New to the list! (I also have a question)

[Calvin Lai]

Hey Seth,

I'm restricting only one item to be dragged into Target. I do that by using
the onDraggingOver event to check if nodes already exist in the drop area.

That's why I want a singular way to access the data member without having to
run through a loop.

P.S. You're the same Seth that's been helping me at stackoverflow, yeah?
