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

[Gotsyk]

Hi, 

I am using Platypus (RL Toolkit 2.0, SVN Rev. 3046) to compose a 
document that has a table in it. 

I've got such error:
File "<work folder>/GeneratePDF.py", line 133, in build_doc
    self.doc.build(self.story, onFirstPage=self.footer_off,
onLaterPages=self.footer_on)
  File

    w, h = flowable.wrap(aW, h)
  File "/usr/lib/python2.5/site-packages/reportlab/platypus/tables.py",

    self._calc(availWidth, availHeight)
  File "/usr/lib/python2.5/site-packages/reportlab/platypus/tables.py",

    self._calc_height(availHeight,availWidth,W=W)
  File "/usr/lib/python2.5/site-packages/reportlab/platypus/tables.py",
line 479, in _calc_height
    w = max(colpositions[t[2]+1]-colpositions[t[0]],w)
TypeError: 'NoneType' object is unsubscriptable

I've found, that in this case, in the line w =
max(colpositions[t[2]+1]-colpositions[t[0]],w) of the tables.py t which
was set t = spanRanges[ji] is None. I've found simple workaround to put
this line into try/except:pass and got correct pdf as result.

Can you point me if I am incorrect with my data?

I've found similar letter about year ago in this list but there is no
result there. If that case was resolved, could you point me to it?

Thank you very much.
