[Zope] StructuredTextTable + PDF

Hi, I'm trying to generate a pdf document from a zope BackTalk book. When I generate the .pdf without any structured text tables it works like a charm. However, when I add a table I get the following error: ---------------- Zope has encountered an error while publishing this resource. Error Type: KeyError Error Value: StructuredTextTable ---------------- The document prints correctly as HTML. I'm new to python/zope/backtalk. Does anybody have any clues as to what may be going on? Here's my software details: SuSE 7.3 python 2.1.3 zope 2.6.1 BackTalk from CVS ReportLab 1.19 Imaging 1.1.4 Any help would be greatly appreciated! -Aaron koadman(at)simons-rock(dot)edu
