[reportlab-users] ActionFlowable usage

[reportlab-users@reportlab.com]

Hi

I am discovering the excellent platypus and pdf package.


I wanted to print a dictionnary like header where the header is 
the first word of the text printed on the page, and used
for this an ActionFlowable object, since as I understood onpage 
hooks passed to pageTemplates cannot be datadriven.

it works but the documents prints everything on a single page 
instead of moving forward.

here is what I did:
-----------------------------------------------

class report(BaseDocTemplate):
   def handle_pageBegin(self,text=''):
     self._handle_pageBegin()
     self.canv.saveState()
     my stuff print text
     self.canv.restoreState()


then from time to time I add a 

ActionFlowable(action=('pageBegin',text to print))

to the list of flowables



at the end I call 

report().build(list of flowables)


if I do not append an ActionFlowable, everything prints fine 
except of course my datadriven header.

If I inserts the ActionFlowables, everything prints fine 
including my datadriven header, but all one a single page.

I insert the Action Flowable everytime I want to ensure the 
header of the next page will be text passed to Actionflowable 
constructor.

but it fails.... though I call the superclass pageBegin before 
adding my stuff


anybody knows why ? or how to achieve data driven header ?


thanks
