I really find it hard to believe it can work without defects :D I have some questions about this though: 1- How does this work for "Remove" operations, let's say you have this list and you want to have "Remove" button on each row, how would that work?. The same question can be asked about "Add New" and both would be solved if there`re such methods on client side, along with some "DataKey" notation. 2- What if I want to use this for a SINGLE item, say a details view for one item instead of list and in-place editing. Would that be treated as a lit containing one item, or there is a another way to do it. I think i know how to load data for single object, but how about load/save? 3- What does the "Change" class give you exactly, how does the API look like? (Is there API documentation somewhere?)

I opted not to get into that detail just yet in the posts :) Using the Sys.Observer to make changes back to the DataContext is in fact neccessary. -JC @Chris

I have been using the Sys.Observer to add changes from other sources back to the DataContext. Do you think this is necessary? or should you be able to create an application that updates everything through bindings.
