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*).
