[Zope] Two problems regarding security, and eval in zope 2.2.4

[Manuel Amador (Rudd-O) Gerente de desarrollo Alpha]

Hello everyone,

I\'m having a little bit of trouble:
http://boeing:8080/manage_access <- traceback of the manage_Access view in the 
ROOT folder


Traceback (innermost last):
  File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 222, in

&lt;lambda&gt;
TypeError: (see above)




that was problem number one.

problem number two.

I\'d like to take the contents of a variable, and they being the name of an 
image object, render it on the web page as an IMG SRC, just like a <dtml-var 
image_id>.  I know this could be done with external python scripts and eval.  
But so far all i get is integeroverflows.



any ideas?  please cc: me because I\'m a little bit busy.  Thanks =)
