[Seaside] updating the contents of a div as a side effect of a liveCallback..

[Rick Flower]

It seems to be that you're not able to do this directly care of a 
message I saw from Michel a while back, but I can't find it now.. and it 
also seems to be I saw code that did something like this, but I'm having 
  a brain fart and can't seem to locate anything relevant..

Anyway, I've got div mixed in with other stuff on a page and when a 
button is pressed I get a liveCallback block running.. I was hoping that 
I could update the contents of the div at that point but Seaside is 
complaining (likely because it's not allowed)..  So, if this is not 
allowed in that manner, I'm sure someone else has written code that does 
the same sort of stuff -- how did you achieve it?  Or perhaps my code is 
just naughty..

As usual-- many thanks in advance!
