[reportlab-users] Fwd: ReportLab problems with CJK

[Alexander Stoffers]

Hi Robin,

i´m not Alexandr Vasilenko but I also reported a problem in the mailing
list, that doesn´t appear in the thread list. I think there is a bug in your
mailing-list system.

I have a problem regarding rowspan columns (I get an error, if the first
column with rowspan attribute is higher than the page is).

Regards,
Alex

Hi Alexandr,

if you want to submit bug reports queries etc etc you can use the reportlab 
users mailing list with a signup here

Your mail is saying we should add a decrement to i after line 764; do you
have a 
fairly minimal example paragraph that illustrates the problem? I don't 
speak/read Japanese, but Andy does and I'm sure a simple example will help 
convince him.
