Harald, thanks for the report. Unfortunately I think the problem lies elsewhere

.......

When I run this script

from reportlab.platypus.doctemplate import PageTemplate, BaseDocTemplate, 
Indenter, SimpleDocTemplate
doc = SimpleDocTemplate('test_platypus_just.pdf')
doc.rightMargin=3*72
styleSheet = getSampleStyleSheet()
bt = styleSheet['BodyText']
btj = ParagraphStyle('bodyText1j',parent=bt,alignment=TA_JUSTIFY)
story=[Paragraph("""<a name='top'/>Subsequent pages test pageBreakBefore, 
frameBreakBefore and
keepTogether attributes.  Generated at 1111. The number in brackets
at the end of each paragraph is its position in the story. 
llllllllllllllllllllllllll bbbbbbbbbbbbbbbbbbbbbb ccccccccccccccccccccccc 
ddddddddddddddddddddd eeee""",btj)]
doc.build(story)


I see this output if I put a print line.wordCount in _justifyDrawParaLineX
C:\Tmp>tparajust.py
5
10
12
2
2


And the split then looks like

Subsequent pages test pageBreakBefore, frameBreakBefore and           (6)

keepTogether attributes. Generated at 1111. The number in brackets at  (10)

the end of each paragraph is its position in the story.
llllllllllllllllllllllllll (12)

bbbbbbbbbbbbbbbbbbbbbb ccccccccccccccccccccccc (2)
ddddddddddddddddddddd eeee (2)

so all the counts are right except the first. I suspect something in the break 
is improperly incrementing the count (or not decrementing it). I'll take a look 
today.
