#162 Rendering invisible controls by callback

[Jawad]

It is impossible to use setVisible(true) on a control
that is defined with Visible="False" in the template by
using a callback.

Moreover, it appears that some useful javascripts
aren't written (so that, for example, a TDatePicker
doesn't work in an invisible Panel, the Calendar.setup
isn't called).

Why not "preload" the javascript at the first page
loading ? Or even add the script to the panel's html
(when flush() is called)
Is there a reason for using registerEndScript or
registerBeginScript instead of simply writing the script ?
