You would have to define dependencies like in [1] but you write so much
code for stuff that should be really simple. But it's possible. By the
way: the new 'UI._templateInstance()' again is based on a global
variable. There's no parameter passed to a helper. But at least the new
hack allows to store data in the instance.

This might seem to be a good idea but it's not that easy because "URLs
over 2000 chars will not work in most popular web browsers" [2]. Also,
it's cumbersome to store some parts, e.g., which dialog boxes are open
or which strings are entered in which forms. And with userdata, you'll
exceed the 2000 char limit easily. Isn't a link to a certain publication
and an additional identifier (like the position in the doc) in the hash
part enough?

Don't get me wrong: having a session isn't bad at all for certain data,
e.g., information about the user's login state. But in my opinion, UI
components such as search fields should not store their data in global
variables.

OK, thx.

No idea about that one. ;)

cheers,
