[weblet] How can a webLet communicate with the hosting html page?

[splash21]

The new revlet format doesn't have the plain text stack code visible in 
the file - (which is a good thing!) - so the old example won't work any 
more.
If it did, 2 or more people hitting the stack at the same time would 
work OK, as they are each served out a modified version of the stack 
(created on the fly): the modified version isn't written to disk, it's 
just fired out to the browser as a deviation of the original and then 
discarded.


I just updated the example for the new plugin and it's working again.  
This version uses the new stack property 'the revletParams' to pass the 
session variable to the revlet (as documented in the 4.0.0dp2 change 
log).  Much cleaner.


The 2 way javascript that you spoke of previously is what we really need 
for this kind of stuff.  I'm looking forward to the next web plugin release.

:)
