RE: Problems with reloading a page with a form

["Howard M. Lewis Ship" <hl...@attbi.com>]

Your rewind (the form submission) must match your rewind.

When controls within the form affect how the form renders, you must double
buffer.

Have the RadioGroup update a secondary property.  Update the real property
from the form's listener method.
