My problem.
Use a session value as part of a select statement to determine what
is shown in a SingleSelectField on a form.
The current problem is getting the session data to be recognized when
setting up the widget named "Task Name". I assume that I have to
request the data for the widget in the Kid template instead of during
initialization, But I am not sure how to do this or even if this is
the correct approach.
