Hi Stefan,
take a look at the _getPageTemplate method in rlwriter.py. Call it with
a string which is a unique ID. The returned NextPageTemplate should be
added to the reportlab story (a.k.a. RlWriter.elements)
Unfortunately this method is not used exclusively throughout the rlwriter.
note:
* the ID should be a string a not a unicode object since that caused
problems a while ago
* call NextPageTemplate before forcing a pagebreak b/c NextPageTemplates
does change the page template for the *next* page
I hope this helps.
Regards,
Volker

Hello,
i added a new Template in pagetemplates.py by basically copypasting
TitlePage and modifying the __init__() and beforeDrawPage() functions.
In rlwriter.py at some point i call:
self.doc.addPageTemplate(MyNewTemplate)
elements.append(PageBreak())
This causes mw-render to go ballistic; for each chapter of the book an
error gets logged

and there is no .pdf file created.
Leaving out the call to addPageTemplate works fine and yields no
errors.
According to e.g. this example for Reportlab:
http://code.activestate.com/recipes/123612-basedoctemplate-with-2-pagetemplate/
it appears that i also have to juggle around with calls to
nextPageTemplate(), the failure to do so seems consistent with the
Traceback above.
Could i get some information about how calls to addPageTemplate() and
nextPageTemplate() are handled in mwlib.rl?
Cheers,
Stefan Birkholz
