I wonder why I can do this on a Page Template:
<tal:b tal:replace='python: here.Texto' />
Where Texto is a adquired property, but not this:
<tal:b tal:replace='here/Texto' />
because zope raises an unauthorized error
How can I solve this point?
You can wait for the next Zope release (2.10) where this is fixed.
The reason: security for "__bobo_traverse__" is much stricter
than for attribute lookup:
In the latter case, the security machinery knows that the value
was obtained by attribute lookup and can apply the security
declarations of the accessed object.
In the former case, the security machinery does not know
which object was really accessed and therefore refuses
to look at the accessed object. This often leads to
The hack in Zope 2.10 checks in this case whether the value
could as well have been obtained by attribute lookup and
then checks along this route.
If waiting is not an option for you, you can also backport
the fix to your Zope version.
In fact all my work depends on this question (this is the reason behind
my nervous. Sorry again Andreas and the rest of people)
Do you know how can I find information to backport the fix?
