exfieldCell becomes see through for Borderless Window

Question

Hi,

From the example of RoundTransparentWindow, I made my Application window to show only the Parts drawn and the transparent parts are cleared. This works fine. But once I create a custom TableView and click its TextfieldCell to edit, the Cell becomes see through. Can anybody help me what would be my mistake with this CustomWindow and CustomView? Without the Window and View customization, my TableView works fine.

I am pasting the link for my sample here. http://www.4shared.com/file/169581867/8e45268d/TransparentTable.html
