[reportlab-users] Problems publishing in Zope

[Florian Reiser]

Hello Sherman,

this error of Zope indicates that Zope wants to store your object with the
doc attribute in ZODB.
Try the following
       report= StringIO.StringIO()
       ...
       # create the document handle
       doc = SimpleDocTemplate(report, pagesize = self.pagesize,
 topMargin=(1.5* inch), bottomMargin=(inch* 2))
       RESPONSE.setHeader('Content-Type', 'application/pdf')
       RESPONSE.setHeader('Content-Disposition',
'inline;filename=%s.pdf'%self.id
       return doc

Then everything should run fine.
