What version of the product are you using? On what operating system?
0.10.1.dev-r668 on Linux

Please provide any additional information below.
It has something to do with the footer directive, the contents directive, 
the PageBreak parameter to the raw:: pdf directive and the subtitle. 
Removing one of the three eliminates the error. The text below also has 
something to do with it. When I remove about 50 lines, the error disappears 
as well.

I can't reproduce it. I added the page break and it produced the attached PDF.

What reportlab and/or wordaxe versions are you using? I tested reportlab 2.3 and 
SVN-3496, both with wordaxe 0.3.2.

Are you using any custom stylesheets? What's the command line you are using?

It looks like I broke page numbers in footers, though.

It was without Wordaxe (as it was in Dutch) and with Reportlab 2.1. So that probably
explains it. Although I can't test it with a newer version of reportlab, as gcc
failes to compile something, both on my Mac (10.4) as on my Linux server (webfaction)..

Will try again sometime.

Page numbers did seem to be broken, yes.

The page numbers is fixed now. I will try to make some testing with RL 2.1, which I 
must confess I have not done in a long time...

Comment 4 by roberto.alsina, Jun 16, 2009

Sort-of-fixed in r672.

It looks like a layout bug in RL 2.1 when using KeepTogether so that you don't get 
orphan titles at the end of pages.

So now you can get those with 2.1, in which case you will have to add manual page 
breaks, which will suck.

So, also added a "your reportlab version is too old" warning ;-)

Please see if it works correctly now and mark the issue as verified.

Status: Fixed

It doesn't throw an error now. But there is no table of contents, instead it displays:

Placeholder for table of contents 0

Comment 6 by roberto.alsina, Jun 17, 2009

Gack. My mistake. Try again in r675

Comment 7 by tinodb, Jun 17, 2009

Nope, now the error is back...:

Ugh, sorry, not really my smartest day.
Try r680, please.

Comment 9 by tinodb, Jun 17, 2009

It now works, with orphaned headers indeed :D

Thanks a lot!
