Re: Flowscript problem?

[Christopher Oliver]

Reinhard,

Try your calculator example again:

This time enter values for both "a" and "b". Then clone the window, hit 
the back button and enter a new value for "b". Return to the first 
window and submit it. You should see the new value of "b" you set in the 
second window. This is the expected behavior.

I believe the reason your example did not work is that the page where 
you submit "a" does not involve an existing continuation (it calls the 
top-level "calculator" function).

Regards,

Chris

Local variables are _shared_ between continuations. Changes 
to the value 
of the variable in one continuation should be visible to another. If 
that is not the case, there's a bug.
   

Try the calculator example as desribed below. But I'm not sure if this
is a bug. IIRC this is not the first time we discuss this but I only
found one pointer:

Does anybody find more on this subject?

P.S.: Moving again a discussion to the dev list

thanks for the reply. But as I understood it, for a single
script there may be multiple continuations at any point in 
time, all corresponding to different page submissions so that 
if you use the browser back button, submitting that page can 
use that particular continuation to restore the intepreter 
state as it was when that page was being submitted the first 
time. 
  

       

sorry, my last answer was too fast: you are right, local 
     

variables are 
   

bound to the continuation. I tried it with the calculator example by 
changing all variables to local variables. I entered a and b 
     

and then 
   

forked my browser window (using IE with Ctrl+N) and jumped back to 
enter a different value for b. If I used local variables I got two 
different results which is the right behaviour. I tested with a CVS 
snapshot from last week (with the latest rhino lib).



     

That's even the example given in the documentation? So
I don't understand your point, I'm sorry. Can you clarify 
further on this? 
  

       

Sorry again.

Try out the calculator examples the way I did. Do you get the same 
results as I got?

Cheers,
Reinhard
