[reportlab-users] platypus/tables.py: TypeError: unsubscriptable object

[Yves Forkl]

Hi,

I am using Platypus (RL Toolkit 2.0, SVN Rev. 3046) to compose a 
document that has a table in it. My script, which seems having worked 
fine with RL Toolkit 1.20, now crashes and provokes the following traceback:


Traceback (most recent call last):
   [in my script: constructing, among other objects, a table; finally
    calling doc.build(Story, onFirstPage=myLayout, onLaterPages=myLayout)]

TypeError: unsubscriptable object


I am kindly asking you to put me on the right track for chasing the 
trouble spot. Does this rather look like a problem with my table set-up 
or like a bug in tables.py?

Which further information about my script would you need to be able to 
give me some more hints?
