Keisuke, Thanks for the quick response, it's always great to hear from you.
Yes, I think you've described exactly the situation. I've got a collection which is tied to a listbox. I've got an automatic selected object. I've got an object display bound to the selected object. I change the source value in the collection and the binding doesn't fire all the way through. Here's where the master data lives: collection.selected_object.element The item I've modified via code isn't displayed in the listbox, it's displayed in a bound variable. The bound variable isn't updating, that's my problem. Is that the bug you're talking about being fixed? For the listboxes themselves, I've been calling *REDRAW* and it works well. I've got a multi-page form and if I switch to a different page and back, the bound variable redraw is done. I guess I could update the contents of my bound variable directly but, honestly, that kind of subverts the whole binding system. Then it's really unclear what the real data is...plus I don't want my code to have to know about binding subscribers.
