  When your cdev gets a 'closeDev' message, your appended dialog items
have already been un-appended from the Control Panel's DITL, and are
no longer valid. If you have text in an editText item, keep a current
copy around (in your private block of storage) and update it whenever
you get a keyEvtDev or a hitDev involving the editText item. That way,
you won't have to read it right at closing time. I don't understand
why you'd want to do a SetIText on a closeDev... you meant GetIText?
