JComboBox with Xith?

I am able to integrate JTextField with Xith but I am having a problem with JComboBox. I suspect this problem is related to the fact that JComboBox uses a popup window. Has anyone been able to successfully integrate JComboBox with Xith? Does anyone recognize the following error from previous experience?
