There is a possible problem in gluon/contrib/fpsf/fpdf.py when the user
leaves an entry blank.
What is the process for submitting this issue in the new reporting
procedure?
51. filler = False
52. for row in db_rows:
53. pdf.cell(25,5,row.case_number,1, fill=filler)
54.
55. pdf.cell(35,5,row.member_id.last_name,1,fill=filler)
56. pdf.cell(25,5,str(row.date_assigned),1,fill=filler)
57. pdf.multi_cell(95,5,*row.description*,border=1,fill=filler )
*<------*
58. pdf.ln(5)
59. filler = not filler
If the description field is empty then the the preceding innocent looking
code results in the following error:
Traceback (most recent call last):

if txt == Null:
AttributeError: 'NoneType' object has no attribute 'replace'
The problem is the following line 730 in fpdf.py
729 wmax=(w-2*self.c_margin)*1000.0/self.font_size
*730 s=txt.replace("\r",'')* <----------------
731 nb=len(s)
732 if(nb>0 and s[nb-1]=="\n"):
733
My BFI (brute force and ignorance) fix was the following:
729 wmax=(w-2*self.c_margin)*1000.0/self.font_size
730 if txt == None:
731 s = ""
732 else:
733 s=txt.replace("\r",'')
734 nb=len(s)
735 if(nb>0 and s[nb-1]=="\n"):
