Jason, Two questions/comments:
1. Are you not creating AsyncToken references from your calls to the ds.createItem and ds.deleteItem? So far you have pretty much what I have, but things get tricky for me when I get the result or fault callbacks. If I have a fault, it gets called 2x for some reason. 2. Regarding the updates to a specific item: Are you not keen on the solution of just pulling the specific item to be updated from the managed collection and updating it and then letting FDS take care of the backend syncronization? Or have you tried a call to ds.getItem() and then modified the resulting object returned after the user has edit it? I'm just making sure you knew that it was possible, although it does not quite follow them same pattern as createItem and deleteItem. I can post code samples if you need them. thanks Bill --- In [email protected], <[EMAIL PROTECTED]> wrote: > > Heya, > > > > I was looking for one too and there doesn't seem to be one.
