Here you will find the solution to your problem: http://lists.canoo.com/mailman/private/ulc-developer/2006/003591.html. It is for ULC 6.0.4 but will work with deprecated methods in ULC 6.1. It demonstrates how to get current focus owner and within that it shows how to get UI half object once you have the basic (Swing) component and subsequently the server side object. Ctrl-P will print the current focus owner. I hope this helps.

Solution A: We could register a focus listener on all Widgets. Everytime the focus changes we get an event and store the current focus owner. Unfortunately this causes to much network traffic and a very high server load, even if we send the focus change event asynchronously. Solution B: We track the current focus owner by registering a property listener at the java.awt.KeyboardFocusManager. This way we get an event for every focus change on the client side. The problem here is that we don't know how to find the apropriate server side half-object from the client side object. Is there a way to lookup an id or something like that for the reference we get in the PropertyListener of the KeyboardFocusManager? My guess is that once we have this id we can pass it to the server (by writing a litle extension) and find the appropriate server side half-object. I added a Snippet to ilustrate the client side of Solution B. TIA for all answers.
