4.0 upgrade issue - ComboBoxItem picklist properties

After upgrading to SmartGWT 4 (from 3.1), I have some ComboBoxItems which have stopped working correctly. I am using setPickListProperties() to pass a ListGrid to a ComboBoxItem. Most properties I set on the grid still seem to work properly, but neither of the event handlers I had applied to the grid are being called anymore. I have a RecordClickHandler and KeyPressHandler set on the grid, and I can't get either of them to fire.

SmartClient Version: v9.0p_2013-07-10/LGPL Development Only (built 2013-07-10)
Running in Chrome

Sample test case attached for RecordClickHandler.

Thanks
