David, I've been messing around with type ahead recently. I came across that as well and I seem to recall the solution was some 'regular' type ahead methodology wired up to the list box. So you'd still have the list object as a separate object on your form and move/show it when doing entry on the listbox cell. Then hide it when done. And if you want to include a 'shadow' TA object (to show what the TA completion would be if you selected it at that moment - looks like the placeholder) it's more complicated by issues of transparency and z-axis locations. Sigh.
I think we're pretty tied to this approach because of 4D's architecture but I'm frequently wrong in those assertions. I've been playing around with the idea of trying to implement TA in a text field, the way the method editor looks up method names for instance. Not really liking anything I've got yet.
