[Zope-dev] 2a3/zclasses: ?define permissions for zsql methods ?!

[Dr. Ross Lazarus]

It may be me - it often is - especially since no one else seems to have
reported this ?

I'm playing with a zclass on zope2a3 (sunos5.2, using zserver/zodb2). It
needs to store and get itself, so it uses some zsql methods. Attempting
to access the "define permissions" management tab for any of the zsql
methods in the methods screen gives :-


  <H2>Zope Error</H2>
  <P>Zope has encountered an error while publishing this resource.
  </P>
  <P><STRONG>exceptions.ValueError</STRONG></P>
  
  Sorry, a Zope error occurred.<p>

Traceback (innermost last):

ValueError: unpack tuple of wrong size

External methods don't even appear to have a Define Permissions tab (but
they're accessible to users so that seems reasonable...)

I've also noticed that while working on methods, clicking on the
"propertysheets" part of a path shown near the top of screen (eg as  
Common Instance Property Sheet at /Control_Panel / Products / SMPLecture
/ lecture / propertysheets / common / Lecturedata  
sends me off into the help frames - maybe bobo knows I need all the help
I can get.
