Bad page numbers when updating table of contents

[Stephane Bonhomme-2]

Hi,

This is my first post here, I'm not experimented with uno but trying to
use it for generating pdf from odt documents on a server.

It works quite well, my server is running debian and a python server
application, so i use pyUno, with openoffice.org 3.1.1 running in
headless mode. I managed to open a document and save it to pdf, It was
quite easy.

The problem I have now appears when updating the table of contents, the
page numbers are not correctly set : they are all changed to the first
table of contents page number (2) (so the index is updated, in the odt
they were set to 1).

There might be several reasons to that :
- as oo.o runs headless, does it automatically updates the page
numbers ?
- I call the update() method on the index just after having called
loadComponentFromURL, do I need to attach my update to an kind of event
(I was wondering if the document were finished to be loaded when I do my
update)

I would greatly appreciate any advice on this way of doing things using
uno. Thanks

Stephane.

AFAIK updating the TOC does not force a re-pagination.
The easiest is to dispatch a ".uno:Repaginate" before, or even an
".uno:UpdateAll".

Nevertheless, I've no idea if this works headless.
Try it and tell.

Hello Ariel,

Thanks for your solution it works fine.

Now I'm trying to set pdf export parameters, but I don't know how to
access the configuration service using pyuno, may be someone could give
me the path....

cheers
S.B.
