I've think I just fixed a bug in the Logger product, but am not sure if it is a good fix or not. def render(self,md): subsystem = self.args['subsystem'] severity = severities[self.args['severity']] if hasattr(md,'this'): summary = self.sectionSummary(md.this,md) else: summary = self.sectionSummary(None,md) The code I stole from SendmailTag.py simply retrieved a string by using self.sectionSummary(md.this,md), but I managed to blow this up with a wierd calling path where 'md.this' didn't exist (A DTML method added to python class with HTMLFile calling a DTML method defined in ZODB). So I added the 'if hasattr' section. Does this indicate a bug in SendmailTag, or in whatever constructs the md object? I havn't been able to trace this strange md object yet but I suspect it is buried in cDocumentTemplate.c (*shudder*). ___ // Zen (alias Stuart Bishop) Work: zen@cs.rmit.edu.au // E N Senior Systems Alchemist Play: zen@shangri-la.dropbear.id.au //__ Computer Science, RMIT WWW: http://www.cs.rmit.edu.au/~zen
