What makes you think you can't move stuff from one window to another?
It is completely possible so long as everything is on the same domain.
There are ways of doing it across domains, but it is *much* more
complicated.
There is a deeper user interface design issue here. Are you attempting
to ensure that if multiple windows are opened to the same table row,
that they will always hold the same information in real time? So that
if a user is editing in one, he will see the same information in the
other as he types?
If so, you are probably working too hard, a better user interface
concept is to trap a request for a duplicate view of the same
information and give focus to the window/tab that is already holding
it. A user will understand and expect this, and it is far simpler to
program.
This being said, the problem falls out like so:
IF WINDOWS ARE IN SAME SESSION, some mechanism must exist so that all
open windows/tabs are identifiable as holding a certain state, so that
you can give focus. If all you do is give focus, you are now finished.
If you want to keep the same information open in two windows, have fun,
you've got quite a bit of programming to do, and you better hire another
support person, you are going to get a lot of weird phone calls from the
users.
IF THE WINDOWS ARE NOT IN THE SAME SESSION, you have a bigger problem,
being of course there is no way to know what is going on. The simplest
case is to disallow multiple logins by a single user, then you prevent
this case altogether. If this is not an option, well...
