This is true for keyboard navigation, however mouse navigation is not cought by this trigger, if the operator clicks on the list dropdown box first.

Very annoying behavior indeed. Makes the drop down list box a pain to use.

I have an if in my when-new-item-instance which checks the count of items in the list. If <=1 then it populates the list w/a query. I figure this will consume only little network bandwidth.

Also add the trigger when-mouse-click to catch mouse navigation, and fire the when-new-item-instance with:

go_item(:system.current_block||'.'||:system.current.item);

This will get the functionality you're looking for, howeverever it does make mouse navigation a little weird.
