StreamResponse on Success

[jose luis sanchez <jo...@m-centric.com>]

Hi all.
I've found myself a problem in an application i've developed using T5.1

There's a page, with 2 datefields, ( From / To ), and a Submit.

The Submit button calls the  StreamResponse onSuccess() method  , 
returning a CVS file with a list of records.

But i'd like to show a label with the total records output, but it looks 
likes there's no page refresh , so the total value is not updated.

Any help on this ?

Thanks.
